However, her apparent obsession with being part of the size zero club, along with fellow actress, Sex in the City star Sarah Jessica Parker, has seen her lose all her curves.

Renee, 38, and Sarah, 42 were seen deep in conversation for 10 minutes after a film party. Maybe they were swopping tips on how to maintain their fat-free figures.

The evolution of Zellweger's rail-thin silhouette is reported to be a result of daily two-hour workouts and 12-mile hikes in the Hollywood Hills.

Her painfully thin look is a dramatic about-turn for the star who famously had to gain two stone for role in Bridget Jone's Diary and the 2004 sequel The Edge of Reason.
