Sexy mom Kate Beckinsale's Underworld catsuit is being auctioned, with all proceeds going to the Entertainment Industry Foundation. The sexy, black leather all-in-one garment will be sold at Premiere Props in El Segundo, California, on February 7.

Other items from the Underworld films, including a medical book, a serum vial and a serum injector are also open for bids.

Vice President of Marketing for Premiere Props Dan Levin said: "Fans and movie collectors will be truly amazed with the rare hero costumes and movie memorabilia from all three 'Underworld' movies that will be up for bid."

The 2003 action-horror film talks about the secret history of Vampires and a type of werewolf known as Lycans. Its main plot revolves around Selene (Kate Beckinsale), a vampire who is a "Death Dealer", or Lycan hunter, due to her hatred for the whole species.
