Forget Matt Damon, ex-EastEnders star Natalie Cassidy got all the attention at The Bourne Ultimatum premiere with her slim new glamorous image. Nat looked a million miles away from her dumpy Albert Square character as she showed off her new body in a figure-hugging black dress. We haven't seen a transformation like this since her fellow 'Enders colleague Charlie Brooks'. Is that the pumping workout music of another celebrity fitness DVD we hear in the background?
