Selena Gomez gives Justin Bieber the cold shoulder at a party

Singer Selena Gomez reportedly ignored Justin Bieber when they found themselves at the same party.

According to a source, Gomez was too busy with her friends and Ed Sheeran to "engage" with the "Boyfriend" crooner.

"Justin and Selena saw each other and didn't engage whatsoever. Selena was too busy enjoying herself with Ed and her girlfriends.

"Selena came with Ed and left with him shortly after Justin arrived. It was obvious she wanted to avoid any drama," a source said.

The party, which was thrown by Bieber's manager Scooter Braun, was as a celebration for Tori Kelly on the release of her new album "Unbreakable Smile".

During the evening, guest Meghan Trainor reportedly took to the stage for a spontaneous performance of "All about that bass" while other partygoers included Cody Simpson and Ashley Benson.
