They got engaged on a rooftop in Abu Dhabi on Thursday.
And Rio Ferdinand and Kate Wright are said to be already planning to have a baby straight after their wedding reports The Sun.
Rio already has three children, Lorenz, 12, Tate, ten, and Tia, seven, with his late wife Rebecca - but the newly engaged couple are reportedly hoping to add to their brood.
A source told the website: 'Rio and Kate can't wait to have a baby. They will want to have one immediately after the wedding. It's what they have always wanted.
'Everyone keeps telling them how gorgeous their kids would be. They want another little cutie just like Rio's three children.
'They love having a big family and a new baby would just be the icing on the cake.'
Rio and Kate announced their engagement on Thursday with a series of adorable photographs.
The pair were pictured for the first time since the footballer's romantic proposal in Abu Dhabi on Friday.
Beaming with delight, the couple enjoyed a rather unconventional celebration as they headed to theme park Ferrari World Abu Dhabi, where they posed for a cosy selfie, before Rio tried the world's fastest rollercoaster.
While living it up at the theme park, Rio's 12-year-old son Lorenz praised his father after he proposed to his girlfriend Kate following two years of dating, while also thanking the star for all she has done for the family.
His delighted son took to the Instagram comments section to pen: 'So glad she said yes I'm so proud of you and Kate love you both so much', to which Rio responded: 'My boy is trying to make his dad all emotional and s**t'.
He also enjoyed an exchange with Kate as Lorenz penned: 'I was so close to slipping up the promise but other than that I am so proud of dad but especially Kate for the things she have done for us love u guys so much'.
She was clearly touched by the message as she responded saying: 'Oh Renz this made me cry we love you more', with a heart Emoji.
The former TOWIE star, 27, accepted the romantic rooftop proposal from the sports legend, 39, during a family holiday to Abu Dhabi after he popped the question.
Rio carried out the marriage proposal in front of his three children, as it was revealed the footballer was given the blessing of his late wife Rebecca to find love again.
Taking to her Instagram account to share the happy news with her followers on Thursday morning, Kate wrote: 'The perfect end to our holiday ... How could the answer not be yes.'
Kate uploaded three pictures of the magical moment Rio popped the question as Lorenz and his siblings looked on.
The stunning cityscape images appeared to have been taken on a rooftop helicopter pad following a night-time ride. Rio's three children could be seen looking on as their dad proposed, before rushing over to hug them both when Kate accepted.
The former England star proudly revealed he had included his kids in his proposal plans, and praised them for keeping the secret for so long.
Posting a sweet snap of the trio watching the special moment, he wrote: 'She said yes. How these 3 kids kept it a secret I'll never know.'
The reality star started dating Rio in early 2017, two years after he tragically lost his wife Rebecca Ellison, 34, following a short battle with cancer.
Rio revealed last year that Rebecca had encouraged him to find love again once she passed, in a conversation with her friend Lisa.
He told The Sun: 'Rebecca told Lisa something in the final weeks of her life. Months later Lisa told me what it was... 'It kills me to think of Rio with a new partner, Lisa, you know it does. Of course it does.
''But you know what kills me even more? Thinking of him alone and lonely. If I don't make it, Lisa, I don't want Rio to be miserable. I want him to be happy.''
Rio has previously admitted that he and Kate spoke about marriage regularly, but insisted they were in no rush to tie the knot. He said: 'We do talk about it, but I'm not going to sit here and give you a date.'
The football pundit also spoke about the positive impact Kate has had on his children since the tragic passing of their mother.
Rio explained: 'My relationship with Kate has helped in that they have got a female in the house now.'
The former TOWIE star has spoken out about her close relationship with the children, revealing they are keen for her to have a baby so they have another sibling.
Speaking in an interview with the Daily Mail's YOU magazine earlier this year, Kate said: 'The kids would like a little brother or sister; they say, 'I dreamt that you were pregnant'. But right now we're just happy with our little unit.'
Kate also explained that she saw the ex footballer and his brood as a package and 'fell in love with them' as soon as she met the trio.
She added: 'I fell in love with Rio, then I met the kids and fell in love with them. I realised, "Wow, my life is going to change". I couldn't be part of his life and not part of theirs.
'I knew it would be a challenge, but if you love someone you go with it and deal with the difficult stuff.'
In spite of her close relationship with Rio's children, Kate has said their late mother is 'irreplaceable' and she works hard to keep Rebecca's memory alive.
Speaking during an appearance on This Morning in May, she said: 'You only have one mum, their mum is irreplaceable.
'There's a special room in the house, for their [late] mum and their nan – they might do homework there for example.
'We always celebrate Rebecca's birthday, we all go to cemetery together. We do talk about their mum, I know a lot more about her than they think.'
The star quit The Only Way Is Essex in April 2017 in a bid to focus on her life with Rio and his children, but although people might not understand her decision, she says it was a no-brainer.
Kate explained: 'Everyone thinks I'm crazy, even my mum was like, 'You're mad!' But I had two choices. I was in this world of drama and in the public eye.
'Then I met Rio, he had children who lost their mum, they didn't have a woman in their lives. Someone needs to be at home and give them love.'
The former reality star confessed the hardest thing has been learning how to discipline three young children and gain their respect and trust.
She said: 'At the beginning one person said to me, 'You don't know how to look after children, you don't have any!' It hurts your feelings when you're trying your best.
'When they break rules, "I'm like, right, you're not having your phone!" If their dad's not at home, I get my phone out and pretend to record them and send it to dad.'
Fans were delighted with the news of Rio's engagement to Kate, taking to Twitter in their hundreds to congratulate the former footballer.
'My heart is melting knowing @xkatiewright and @rioferdy5 are engaged HOW CUTE ARE THEY', one person wrote.
Another enthused: 'I'm actually so happy for @rioferdy5 and Katie Wright I could cry', another fan shared, adding dozens of heart emojis.
Rio has been candid about the difficulty of becoming a single parent following the tragic death of his wife Rebecca Ellison.
Rio met Rebecca, a former fitness trainer and accountant, while he was at West Ham United in the late 1990s. The pair married in the Caribbean in 2009.
Rebecca was diagnosed with breast cancer in 2014 but had appeared to be clear of the cancer following treatment
But a scan earlier in 2015 revealed it had returned and spread to her bones and she died just five weeks later on May 1.
The BT Sport pundit opened up about his loss in a BBC documentary - Rio Ferdinand: Being Mum and Dad, in which he explored ways of managing grief.
The programme won the Single Documentary Award at the TV BAFTAs 2018.
He broke down in tears as he picked up the award last year, saying: 'I didn't do this for any other reason other than my three kids. The worst thing to come out of this is that I get quite emotional now.
'I'm not quite used to it. This documentary has given something to my three kids.
'This documentary has propelled me forward into a period of happiness where my kids are happy I've got a beautiful girlfriend. Thank you, BBC, thank you very much.'
He earned the respect of the nation with his frank discussion of life as a widower in the documentary.
'This is one of the only things in life that we're going to go through together, where I haven't got the answers for them, and that's quite a worrying, daunting thing', he said in the programme.
'When they don't speak, it's difficult sometimes, you're just sitting there going like 'what are they thinking? Where are they? Are they worried, are they happy, are they sad?''
Rio added that while he is 'desperate to know' what his children are thinking, he doesn't 'want to scare them.'
erdinand was still playing professional football for Queens Park Rangers when Rebecca lost her battle with breast cancer, but retired the same month without playing a further match.
'I don't think I've grieved properly,' the star said in the documentary. 'I've not given myself that time to sit down and really flush everything out and go through it.
'As footballers, we often talk about missing important games through injury as if it was the end of the world.
'Believe me, it isn't when compared to your wife and mother of your children dying of cancer at the age of 34.'
In a previous interview with The Sun, he admitted his wife's battle was a private one, as she opted to stay out of the limelight for the sake of her family.
'Rebecca was an incredibly brave woman and a very private person who didn't want anything about her illness to appear in the media while she was fighting for her life,' Rio noted. 'Only a close-knit group of family and friends knew.'
