Christina Hendricks almost spills out of her corset as she launches Vivienne Westwood store in LA

Spring was certainly busting out all over when Mad Men star Christina Hendricks helped Dame Vivienne Westwood launch her new flagship store and Palladium Jewellery Collection in Los Angeles last night.

The 35-year-old star had squeezed into one of the designer's iconic corset tops and her famous embonpoint was almost spilling out of it.

The stunning red head, who plays Joan Holloway in the show, was also wearing cigarette pants - rather aptly for a Mad Men actress - black peep toes and a gold sparkly oak leaf brooch from the range.
