Samuel L Jackson hosts star studded charity ball

Simon Pegg, Colin Firth and Pixie Lott were just some of the stars mingling with the dinosaurs at London's Natural History Museum, at a charity ball organised by Hollywood actor Samuel L Jackson.

Actress Margot Robbie, singer Pixie Lott and Desperate Housewives' Jesse Metcalfe were also on hand to raise money for a charity which aims to raise awareness of male cancers.
