Are Selena Gomez and Justin Bieber reuniting?

Prying minds definitely want to know and Selena set the rumor mill on fire on Wednesday night when she hit The Biebs' Purpose World Tour concert at the Staples Center in Los Angeles.

The 23-year-old songbird was reportedly hanging out backstage with her ex-boyfriend and enjoying his show. This news comes just days after Bieber posted a throwback photo of himself and the "Hands to Myself" singer locking lips back when they were still together.

Sources tell E! that the duo are considering giving their romance another chance and have been talking about getting back together. Sources added, the two seemed very comfortable together at the concert and looked really happy.

Only time will tell though if there are still old feelings there. Either way, Bieber definitely has reason to celebrate. His Wednesday concert was swimming with big-name celebs. Kim Kardashian, Kanye West, Kourtney Kardashian, Kylie Jenner, Kendall Jenner, Tori Kelly, Rita Wilson and more stars turned out to support the "Sorry" singer.
