Bieber Raises Eyebrows As He Posts Pic of Selena Gomez

It's not a "crazy throwback" photo (as Justin describes is), but the fact that he chose to post it on a Saturday (and not the customary Friday or Thursday), some hours after Selena Gomez was reportedly spotted kissing Niall Horan at Jenna Dewing Tatum's 35th birthday party has raised a few eyebrows...

According to sources speaking to Us Weekly: "Horan, 22, and the “Good for You” singer were locking lips in full view of guests at Jenna Dewan Tatum’s 35th birthday bash in Los Angeles on Friday, Dec. 4. 'Niall and Selena were kissing in the middle of the club, in front of everyone'...

Another source noted that the pair spent the entire evening together. 'Niall and Selena definitely seemed very close and like they were together... 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'."

They were also reportedly flirting up a storm at the Jingle Bell Ball before Jenna's party. Oh, and there was this photo.
