Firth pities Zellweger

English heart-throb Colin Firth pities his Bridget Jones co-star Renee Zellweger for all the media attention she receives over her fluctuating weight.

The Oscar-winning actress piled on the pounds to play Helen Fielding's 'singleton' in the 2001 hit Bridget Jones' Diary and this year's sequel Bridget Jones: The Edge of Reason, but immediately lost the weight after filming ended.
