Malibu Beach had a Memorial Day Beach Party where celebrity couple Jake Gyllenhaal and Reese Witherspoon attended as well as Kate Beckinsale, her husband Len Wiseman and her daughter.

Robert Downey Jr. tips his hat to pappers, with his Iron Man lunchbox as he heads to the party and his Sherlock Holmes director Guy Ritchie also attends.
