Robbie Williams Walks LA's Streets In Gorilla Costume

Robbie Williams has caused more rumours that he is becoming more eccentric, after he was spotted walking round the streets of Los Angeles in a gorilla costume.

Photos were taken of the singer after he bought the novelty costume for $60 from a Hollywood fancy dress store and then proceeded to walk the streets in his unusual new outfit.

This behaviour is worrying friends of Williams, who has apparently become reclusive in recent months and become obsessed with aliens.

Robbie's friend Tara Palmer-Tomkinson tells The Daily Star: "Of course I'm worried for Robbie. He's a genius and when you're that smart and have been in the public eye for so long, you want to escape."
