That Old Thing Back? Selena Spends The Night At Bieber's! (PHOTOS)

The beauty of being single is that you can do whatever you want!

Even if that means going to see your ex-boyfriend.

And that's exactly what Selena Gomez did this weekend when she was photographed leaving Justin Bieber's house, just a month after they ended their on again-off again relationship.

But does the Spring Breakers actress want that old thing back?

A source confirms to Us Weekly that the former lovebirds did indeed see each other. It's unknown, however, whether their reunion was romantic in nature. "It never ends," the insider tells Us. "We'll see. It's such drama with them."

While there's no word on whether the couple is back together, we do know one thing: People have needs.

One of Justin's tweets caught our attention and raised some eyebrows: 

"i put on my raincoat..."

If you weren't aware, Bieber just came out with a song called "Yellow Raincoat," which is all about his relationship with Selena. Clearly he's referencing something going down with his ex-girl. 

Bieber, you naughty boy, you!
