The pair have been rumoured to be more then just friends following her recent break-up with boyfriend Casper Smart, and a source shared with Us of their night on the dance floor with friends: ‘Maks was whispering into her ear and hugging her.’

‘They looked very flirty with each other…She had a huge smile on her face and looked like she was having a great time,’ the source elaborated.

On top of dancing to Jay Z’s 99 Problems, the duo even held hands and exchanged an embrace as they parted ways, Us Weekly adds.

At the end of the night, the Dancing With The Stars professional ‘left with a male friend,’ while Jennifer kept with her group of companions.

The reported sighting comes after Jennifer’s recently finalized divorce from ex-husband Mark Anthony and a recent spilt from ex-boyfriend of over two years, Casper.

The Get Right singer addressed her relationship status in a town hall interview with Sirius XM’s Morning Mash-Up, concluding she wasn’t yet ready to jump back into the dating world after her break-up.

‘Listen, I’m good right now. Let’s just say we just got out of a relationship, there needs to be time for reflection and alone time. So, for sure, that’s where I’m at right now,’ Jennifer said with a laugh.

In early June, a tweet posted by radio station Qburgh read: ‘@JLo broke up with Casper Smart on FRIDAY and is already dating someone new! (And he’s GOOD LOOKING! FINALLY!)’

The story referenced a blossoming romance between JLo and Maksim, though the singer shot the rumour down.

‘@Qburgh No I’m not.  #rumors #nottrue #AKAinstoresJune17  :)’ Jennifer tweeted.

‘They are friends,’ a source revealed to Us Weekly.

‘She doesn’t have a second to date anyone right now, and it is definitely not romantic with Maksim.’
