As if the fact that Justin Bieber and Selena Gomez have broken up wasn't enough to be going on with, they've been toying with our emotions EVEN MORE by supposedly being spotted together at last night's American Music Awards.

Justin Bieber and Selena split?

There's so much will-they won't-they that we really don't know where to start, but apparently the pair met up the talk about their differences over dinner at the weekend.

Apparently things didn't end too well though and it's been reported that they had a bit of a barney at the Yamato Japanese restaurant in LA.

“All of a sudden someone was yelling and I was like how embarrassing to have a fight in public," a source told Hollywoodlife. "Then I realized it was Selena Gomez and she was having a fight with Justin Bieber. She was so mad she was crying and just stormed out of the restaurant.

"Justin followed behind her and looked upset. He looked kind of shocked like ‘what just happened?’ I felt really really sorry for them.”

To be fair, we'd probably be feeling a bit mardy if all we got for dinner was a bit of raw fish too.

Anyway, despite apparently having a bit of argy bargy, it seems like they might have made it up and after Selena headed out for a girls night with BFF Taylor Swift, the Biebs was spotted arriving at her LA home.

Unfortunately things weren't happy clappy enough to get them on the red carpet together at the AMAs, with the Biebs taking mum Pattie Mallette as his date instead.

There might be more to all this than meets the eye though and to make things about a billion times more confusing, a reporter from E! online apparently spotted Selena backstage holding hands with the Biebs later in the night, so maybe she did turn up after all.

"Guess who apparently showed up at the end of the AMAs... Selena Gomez. She was spotted backstage holding hands with... Justin Bieber," he tweeted.

In conclusion we'd like to say that we have NO FREAKIN' CLUE what the heck is going on. If somebody would care to sort these star-crossed lovers out, we'd appreciate it.

Thanks.
