Pasta & milk made Justin Bieber throw up on stage?

Were you wondering why Justin Bieber chucked his guts up on stage? Of course you were. This is 2012, we want to know everything about everyone.

Poor J-Biebs was performing in Glendale, Arizona when he had to stop singing, turn away from the audience and vomit.

So what was wrong? Well, according to a source, Justin is a little embarrassed about what happened.

“Justin had pasta and milk about an hour and a half before he went on stage,” the source told “He’s a bit embarrassed but he’s fine, the kid is tough and knows how to laugh at himself.”

“Milk was a bad choice,” Justin tweeted after the show – a line from hit movie Anchorman: The Legend of Ron Burgundy.

It’s nice to see Bieber has a sense of humour about it all.
