They've had a bit of an 'are they, aren't they?' love affair in recent months.
But it appears Khloe Kardashian and French Montana could be on the more 'on' side of things in their relationship, as the two have been on holiday together with friends this week.
The 30-year-old beauty has been in Key West, Florida, along with the rapper, his friend Chinx Drugz and her best pal Malika, among others.
While the Keeping Up With The Kardashians star has been quiet about her whereabouts on her social media pages, French Montana and Chinx have posted pictures on their Instagram accounts that reveal their idyllic getaway.
In one shot posted by Chinx, Khloe is seen letting her newly-blonde hair down while on a jet-ski.
She looks the picture of relaxation in the snap, joined by the rapper who is also having a whale of a time on the sea vehicle.
In another image shared by French Montana himself, he is seen on a plane - holding up a wad of cash - making his way to the luxurious destination with Malika sat in front.
According to TMZ, the on-off partner of the reality TV star also greeted her with a bouquet of red roses as she arrived for the holiday at the weekend.
And, while they aren't officially back together at the moment, a source told the site: 'I wouldn't be surprised if they fall back into old habits.'
Their seemingly friendly getaway comes just weeks after they enjoyed Valentine's Day together, sparking rumours that their romance is definitely back on.
A series of Instagram posts made by the TV star - who was previously married to Lamar Odom - showing gifts from her apparent man, as well as a picture of herself with him amid a group of friends.
Khloe posted an affectionate snap with her love online, as well as the gorgeous gifts she received for Valentine's Day.
'Happy Valentines Day!! (rose)(rose)(rose) and (diamond)(diamond)(diamond) #LuckyLady,' the beauty wrote with a picture of a huge bouquet of red, white, and pink roses.
The reality TV star also showed off her glittering new pink gold Cartier Love ring with diamonds - and this wasn't the first time the rapper has spoiled her with lavish gifts.
French threw her an elaborate birthday in June last year and showered her with costly presents such as a $25,000 ring with natural green Colombian emeralds and natural yellow canary diamonds.
But after eight months of dating, Khloe and French ended their relationship in September 2014. They briefly reconciled in November, yet things quickly fizzled out.
Now, it seems the two may just be back on and going strong, recently being spotted together on multiple occasions, including their Key West vacation.
This is the first serious relationship Khloe has had since splitting from her ex Lamar Odom.
Khloe tied the knot with former Los Angeles Lakers player in 2009, but she filed for divorce in December 2013, following months of speculation over the state of their relationship.
