Justin Bieber shares Selena Gomez photo after ex seen ‘hugging and kissing' Niall Horan

Selena Gomez and Niall Horan are grabbing the dating headlines recently after they were seen having dinner with a group of friends after the American Music Awards (AMAs) last month. The pair has yet to comment on the real status of their relationship. However, a source claimed they were once again seen getting intimate with each other during Jenna Dewan-Tatum's birthday party on Friday, Dec. 4. Justin Bieber on the other hand has been posting throwback photos of his ex-girlfriend on social media after he was seen serenading her at a Beverly Hills hotel lobby.

Horan, 22, and Gomez, 23, were reportedly showing a lot of PDA while at Tatum’s birthday bash at Bootsy Bellows in Los Angeles. A source told E News that they were seen hugging and dancing close together. Another insider likewise told US Weekly that the pair seemed oblivious of the other people around them and were seen “kissing in the middle of the club, in front of everyone.”

They reportedly seemed very close with each other that night. They acted like “they were together” and stayed by each other’s side the entire time.

“Niall got there first with his bodyguard, then the next thing I know, I looked over and Selena was there. They were very close together, talking and whispering,” the eyewitness told US Weekly, adding that they left together, with Gomez seen grabbing Horan’s arm as they left the party.

The One Direction singer later took to his Twitter to share his photo with Gomez and with some of Tatum’s friends at the party. Horan is seen with his hand on the “Same Old Love” singer’s shoulder.
