Justin Bieber hits a new low on South American tour

Aye carumba! Justin Bieber is having a real drag during his tour of South America.

The Baby hitmaker has had the week from hell: he's been charged with vandalism in Brazil, filmed by a snooping girl while snoring in his hotel room and now he's come down with a nasty case of food poisoning.

The star was left running for the bathroom just hours before he was set to take to the stage in Buenos Aires, Argentina on Sunday. He battled on to begin his show but his ill health got the better of him and he left the stage in the middle of his performance.

However, it wasn't a completely awful night - Justin received news from Amsterdam that he had been named Best Male at the MTV European Music Awards.

He tweeted fans: "Sitting here with food poisoning and heard we won #bestmale at the #EMAs. Thanks everyone."

The pop star added, "Argentina been a rough day but the show must go on. I'm coming...This sucks.... Not feeling so good. Actually pretty sick. Pulling it together. Argentina we got a show to do. Love u (sic)."

His best pal, video producer Alfredo Flores, also took to the site to heap praise on his friend's determination not to disappoint fans.

Flores added: "Going against doctors orders he still went on stage tonight. The last thing Justin ever wants to do is let his fans down... He gave it his all but health always comes first. Proud of him for even getting out there and giving it a go. Today was a rough one."
