The sexy young things are said to have been KISSING at a showbiz party on Friday night (4 December) and reports say they didn't seem too bothered with who saw them!
According to E! News, the stars enjoyed their PDA at Jenna Dewan-Tatum's 35th birthday party.
The actress wife of Channing Tatum celebrated her special day at Bootsy Bellows in Los Angeles surrounded by family and showbiz friends including Ashton Kutcher and Mila Kunis, Jessica Alba and Cash Warren, Adam Levine and wife Behati Prinsloo, Lea Michele and Jamie-Lynn Sigler.
Former Disney star Selena, 23, and One Direction's Niall, 22, were reportedly seen dancing close together all night, kissing and hugging says an eyewitness.
Both singers had performed earlier in the night at 102.7 KIIS FM's 2015 Jingle Ball at Staples Centre and are believed to have left the event together.
Another source told US Weekly: "Niall and Selena were seen kissing in the middle of the club, in front of everyone [...] The were very close together, talking and whispering."
The insider then adds that the couple "left the party together".
We have to admit, we're just a bit excited. If it's true, these two make a seriously cute pair.
They were first linked last year, while new rumours began again last month when they were photographed dining together at Nobu in Malibu.
Of course there's the slight complication of Selena's ex-boyfriend Justin Bieber, who might not want to let her go that easily.
Justin has previously described Selena as "the love of my life".
They were fresh-faced teens when they started dating in 2011, but their relationship was a rocky one and they finally called it quits in January 2014.
