They have been an item for a number of weeks now, but have kept their romance low key.
But it looks like Joe Jonas and Gigi Hadid now don't mind who sees they are more than just friends after the singer posted a neck licking PDA on Instagram.
The shot, 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.
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.'
After the dinner the pair hit up the nightclub Up & Down, where Nick was set to DJ.
However the evening got shutdown by police and he didn't get a chance to take to the decks.
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're together 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 togther in May and have been to a number of events, but not yet posed officially as a couple.
Since first grabbing lunch in May, the pair have attended numerous events together and traveled to London and Rhode Island with pals Taylor Swift and Calvin Harris.
