Selena Gomez had a run-in with her ex-boyfriend Justin Bieber when hitting up The Nice Guy in West Hollywood with her pal Ed Sheeran on Thursday night, June 25. Selena managed to avoid Justin at the event held in honor of Tori Kelly's "Unbreakable Smile" album release party.

Selena attended the party wearing a beige long vest paired with a striped top and skinny leather pants. Her hair was styled in voluminous curls. She completed her look with a brown fringe bag and black booties. Justin donned a black hat, a plaid shirt paired with a black tee, pants and shoes. Ed, meanwhile, sported pink tee, black pants and blue shoes.

Other celebrities in attendance included Meghan Trainor, Ashley Benson, Cody Simpson and The Weeknd.

An eyewitness told Us Weekly that Selena and Justin "didn't talk" during the party. "Selena came with Ed. Bieber came with Scooter [Braun]," the source added. "Justin and Selena each noticed that the other person was there. But they didn't go over and say hello."

Selena reportedly didn't stick around for too long after Justin arrived. The "Good for You" songstress left the party with Ed while Justin left separately. Selena and Ed were spotted stopping by a local 7 Eleven to grab snacks before heading back home.

On Friday night, Justin gave a shout out to Ed, The Weeknd, and Cody on Twitter but not to Selena.

Good times last night @theweeknd @edsheeran @CodySimpson. Hey @ToriKelly do u ever miss a note??
