Uh oh. Is Justin Bieber's brain about to explode since his ex Selena Gomez and Barbara Palvin, the Victoria's Secret model that reportedly came between them, were chatting it up at the 2013 Golden Globes?

Jelena have been on-off since late last year and while the status of their relationship seems perpetually up in the air, the latest is that she shut it down last week in effort to stop the drama that follows the relationship and The Biebs.

Sel and Barbara were both on hand for the Globes and were photographed deep in conversation. Were they discussing The Biebs? Smiling through gritted teeth while exchanging barbs over The Biebs? They posed nicely, but who knows what the lovely ladies were gabbing about. Chances are it involved their bone of contention. Or not.

We're not sure why either starlet was at the Golden Globes, since neither were up for awards. Just sayin'.

Fans were also suggesting that Sel was a bit tipsy at the afterparty. She was talking super fast, slurring her words and was a bit giggly during her interview, which you can watch below.

Sel was living it up with her girlfriends at the event, since she reportedly wants to give up guys for a while in order to get her head back on straight now that's she's free of a relationship.

A source told RadarOnline, "Selena has sworn off men for the time being. She just wants to be free to do what she wants to do and not have to worry about anyone else but herself. It’s been a while since she’s been able to do that."

The source continued: "So, for now, she wants to go out with her girlfriends or have slumber parties at her home without being committed and in a relationship with a boy."

Yeah, but don't the rules change when "a boy" is the one and only Justin Bieber?
