VIDEO : Leonardo DiCaprio Outbids Paris Hilton for a Chanel Purse in Cannes

Leonardo DiCaprio is a mama's boy!
The Oscar nominee dropped more than $13,000 on a Chanel purse for his mom while attending the Heart Fund Gala in Cannes. A blue Neoprene flap bag with embroidered flowers, the purse was sold as part of an auction to benefit the charity. Leo told reporters that he purchased the accessory for his mom.
Cue the awwws.
But the Inception star, 40, didn't win it too easily. He was in a bidding war against Paris Hilton, 34, who was just as anxious to take home the bag as he was. Even though she didn't win the coveted bag, she didn't play the role of a sore loser. A source told People that both she and Leo were enthusiastic members of the auction all night long.
"Paris was great. She bid on many things, and Leo did too," the source said. "Both her and Leo were so active during the entire auction. It was really nice to see."??
