They are the on/off couple that just couldn't seem to stay apart.
And now rumours have emerged that Cody Simpson, 18, and his ex girlfriend Gigi Hadid, 20, were reunited last week at a New York party.
The New York Post quotes an onlooker suggesting that the encounter got pretty hot and heavy, telling the paper that the pair were kissing, claims which Gigi has since denied.
'They were together the whole night, sitting on a couch, basically on top of each other,' the eyewitness told the publication.
'They were being very affectionate, and kissed more than once. Just smooching, not a hard-core make-out sesh.'

However, a rep for Gigi has poured cold water over the rumours, telling The Post that Cody attended the bash with another girl, and that
Gigi and her former beau only 'talked briefly' at the event.
The following night the Sports Illustrated model was reportedly seen with her new man Joe Jonas at The Game nightclub to celebrate the launch of the new app, Wine ’n Dine.
The latest report comes after Joe shared a rather saucy shot of Gigi licking his neck last week.
The snap, taken on Thursday, shows the blonde model running her tongue along the 25-year-old's neck.
Joe, wearing a T-shirt emblazoned with the word 'Daddy' stood still with a small smile playing on his lips.
Both of their faces were cut off from the photo so their noses and eyes could not be seen.
Joe captioned the shot: 'Call me.'

The pair were at a Pulp Fiction themed dinner in New York when the picture was taken, the night after Cody and Gigi's chance encounter.
According to Us Weekly a source said: 'They were being super-cute and cuddly the whole night.'
The loved-up couple enjoyed burgers, milkshakes, and fries at the soiree.
The insider added: 'They were the first couple to get on the floor and start the dancing for the twist contest.'
It was after their dinner that the pair hit up the nightclub Up & Down, where Nick was set to DJ.
Despite the pair refusing to confirm they are an item, they have been posting a number of Instagram shots of themselves together - namely at Taylor Swifts July 4th weekend away bash.

Then Joe's brother Nick, 22, let the cat out of the bag confirming his brother was dating the 20-year-old.
He told E!: 'I like them together. It’s a good thing.
'Joe and I are best friends. We're each other's support system and closest friends, so naturally I'm gonna see a lot of her because they'retogether and it's great. I'm really happy for them. I think they seem very happy together and it's good.'
The pair were first seen together in May and have been to a number of events, but not yet posed officially as a couple.
