British actress Kelly Brook suffered an embarrassing wardrobe malfunction this week (beg08Apr13) when she left home with her dress unzipped.

The Piranha star stepped out of her London house on Wednesday (10Apr13) to attend the taping of a Tv show wearing a glamorous bright blue frock.

She smiled for the waiting photographers, but Brook failed to realise her zipper wasn't done up and left her dress gaping at the back, revealing her black bra to the world.
