Annalynne McCord's sister, Angel McCord, made a splash at Britney Spears' charity dinner last Wednesday when she stripped off and jumped into the pool to gain a $15,000 donation.

The donation will go towards benefitting the St. Bernard Project. Spears held An Evening of Southern Style at a private residence in Beverly Hills, California on the Wednesday to help raise money for the charity.

The organisation was set up in 2005 after a devasting storm destroyed Spears' home state of Louisiana and aims to help the people that were left homeless after the disaster.

Angel McCord, a budding actress who grew up in the southern state of Georga, boosted donations by agreeing to undress and dive into the pool if someone would make a $15,000 donation, according to the New York Post gossip column.

One partygoer says, "A guy stood up and said, 'Done!' She took off her jewellery, called her friend over to unzip her dress and jumped in."
