Exhaustion causes Kristen Stewart to collapse?

A report has suggested that Kristen Stewart has collapsed due to exhaustion.

Her family are said to be worried about the stress that is being piled on the Twilight actress, with the new movie and the media speculation about her relationship with Robert Pattinson.

A source reportedly told heat magazine: ‘Her family is worried. She’s told them it is killing her.’

‘Kristen has been looking pale and drawn in the last couple of weeks. Her stylist told her to get a lighter hair colour to try and hide how ill she was looking.’

‘At one point, she was so gaunt that her eyes were almost popping out of her head.’
