The singer, 23, was reportedly spotted showing PDA with One Direction's Niall Horan at a party in Los Angeles on Friday, E! News reports. The pair attended Jenna Dewan-Tatum's 35th birthday bash at Bootsy Bellows alongside a slew of other stars, including Horan's bandmate Louis Tomlinson, Ashton Kutcher, Mila Kunis, Adam Levine and Dewan-Tatum's husband, Channing Tatum.
E! reports that the pair was spotted kissing, hugging and dancing close to one another. They also took a photo together with a group of pals.
It was a busy night for the two young singers as they both also performed at 102.7 KISS-FM's Jingle Ball 2015 earlier in the evening. Horan was joined by his castmates at the concert when he chatted with PEOPLE about his New Year's resolutions.
"I'm going to train, succeed in the gym this year. I always do it when I'm on tour and then when I get home, I'm crap," the 22-year-old said. "Yeah, I would like to succeed properly and get the job done."

This isn't the first time that the pair have reportedly linked up – they were spotted dining with Horan's 1D band members in Malibu late last month.
The pair have quite a few mutual friends – Horan's bandmate Harry Styles previously dated Gomez's friends Taylor Swift and Kendall Jenner. Another Swift squad member, Ellie Goulding, also admitted that she went on a few dates with Horan after romance rumors popped up.
Earlier in November, Gomez sparked rumors that she had reconciled with her on-again, off-again boyfriend, Justin Bieber, when the 21-year-old crooner was spotted singing "My Girl" and "Sorry" to his former flame at the Montage Hotel in Beverly Hills.
