Caught ya!

A number of spies spied Selena Gomez in the crowd at Justin Bieber's concert at the Staples Center on Wednesday night. Are the two getting back together AGAIN? Really anything is possible with these two crazy kids!

Seeing her at the show definitely has our minds swimming -- and we bet the Biebs has been swimming through Selena's mind after the popstar posted a throwback photo of the former flames kissing on Instagram.

Along with the smoochy snap, Justin wrote "Feels." We have a feeling that the popstars still want to feel all over each other -- and it seems like that's bound to happen yet again since both singers are currently single.

It's amazing -- all it takes is an Instagram photo and the "Hands to Myself" singer is back in her former beau's grasp!

Interestingly enough, Beib's summer hangbang Kourtney Kardashian was also at the concert -- for a second time this week. JB has so many exes to choose from!
