And just when Justin thought his week couldn't get any busier, he's now caught a major dose of the skitters.

The Boyfriend crooner had a hurty belly ahead of a gig in Argentina last night and it's not yet known how he picked up the bug. We may have a few theories.

He broke the news of his tummy woes on Twitter after hearing of his Best Male win at the MTV Europe Music Awards in Amsterdam last night, posting: "Sitting here with food poisoning and heard we won #bestmale at the #EMAs. Thanks everyone. (sic)"

The star, who missed the awards ceremony due to work commitments, reassured the Argentinian 'Beliebers' that the gig, which was part of his 'Believe' tour would still go ahead, 'cause he's not adverse to unleashing the contents of his stomach while onstage. What a little trooper.

He tweeted the following, obviously in a bid to whip his legion of Beliebers into a whirlwind of excitment: "Argentina been a rough day but the show must go on. I'm coming. This sucks. #sick food poisoning."

The 19-year-old singer has also reportedly been evicted from the Hotel Faena in Buenos Aires due to his rowdy fans who have disturbed other guests and acted the maggot with hotel property.

This rounds off an eventful few weeks for the teen, who ran into a spot of bother in Brazil after spraying graffiti on a wall. And, yes, he was also filmed snoozing by Brazilian 'mystery woman' (read into that what you will) Tati Neves, who posted the video on YouTube (wrong aspect ratio alert), and claimed she enjoyed the odd doob or two with him.
