She really does have a terminal case of Bieber fever!

Justin Bieber and Selena Gomez are the most on-off couple in Hollywood, and all signs point to them being ON again after this Snapchat video surfaced of the pair hanging out together with mutual pal and pastor Rich Wilkerson Jr.

Although you only see the "Come & Get It" singer for a brief second, and if you blink you might miss her, she is seen smiling and laughing in the background as The Biebs does a rap about God.

We guess poor Selena thinks JB might be done banging random girls. We give it two weeks before she's back to crying on Taylor Swift's shoulder and eating Ben & Jerrys.

If he was your boyfriend, he'd never let you go.... well, yes he will, until he's bored and his side chicks are busy!
