Just when excitement over Justin Bieber’s “feels”-inducing Instagram throwback pic was starting to die down, the singer’s ex, Selena Gomez, showed up to support him at his Los Angeles concert on Wednesday. An eyewitness told ET the singer looked "gorgeous and happy" at Bieber's Purpose show.

The Staples Center’s official Twitter account announced that Gomez -- along with Kanye West, Tori Kelly, and a few members of the Kardashian-Jenner clan -- was attending the third night of the Biebs' L.A. concerts, but they certainly knew which name to list first to whip fans into a frenzy.

Bkstg, a music fan app, also claimed to have run into Gomez “in a hallway” at the show.

Eventually, a couple of lucky fans spotted Gomez watching the show from the safety of the sound booth, but she moved around the whole concert.


Unsurprisingly, Bieber fans had something to say about the singer’s presence at her ex’s concert:
