Selena Gomez and One Direction band member, Niall Horan, were seen kissing in public as both attended Jenna Dewan-Tatum's 35th birthday bash. The party was organized by Channing Tatum, but it seemed like the two love birds had completely stolen the spotlight.

Gomez and Horan reportedly spent the whole evening without leaving each other's side, according to a source who had spoken with the US Weekly. "Niall and Selena were seen kissing in the middle of the club, in front of everyone. Niall and Selena definitely seemed very close and like they were together," the source revealed.

The insider who was also present at the party said that Niall got there first with his bodyguard. "Then the next thing I know, I looked over and Selena was there. They were very close, talking and whispering," the source added. The source said the new would-be couple left the party together. "She grabbed his arm on the way out and held onto it," the source said.

E! News is reporting the same. Gomez and Horan "were all over each other," the report said. The pair was dancing close together while kissing intermittently on the lips. There was also lots of hugging, according to a source who had spoken with E! News.

The source further revealed that Both Gomez and Horan performed at 102.7 KIIS FM's 2015 Jingle Ball before the party. Horan reportedly stayed and waited until Gomez finished her stint. The pair then left together, the source said.

The event where Gomez and Horan were reportedly smooching each other was a joint birthday party for Jenna Tatum and her bestfriend, Emmanuelle Chriqui. The party was organized and thrown by their respective husbands, Channing Tatum and Adrian Bellani. Also spotted at the birthday bash were Adam Levine and Behati Prinsloo, Ashton Kutcher and Mila Kunis, Jamie-Lynn Sigler, Jessica Alba and Cash Warren, Kevin Connolly, Jerry Ferrara, Mina Tobias, and Lea Michelle.

The shocking report came as Joe Jonas had given Gomez an early Christmas gift, according to a report from Teen Vogue. After her performance at WiLD 94.9's FMs Jingle Ball 2015 at Oracle Arena on Thursday, Gomez was surprised to find a huge Christmas stocking on her bed.

She posted a photo of herself beside the early Christmas gift on Instagram and she tagged Jonas. The caption read: "After the show is the after party. Thank you@dnce for my stocking!!!" The photo showed that the stocking was flowing with gifts. There were stuffed toys, lotion and a book of word searches.
