Leonardo DiCaprio outbids Paris Hilton for an expensive Chanel bag for his mum

Leo DiCaprio made the winning bid for a Chanel bag at the Heart Fund Gala auction on Monday at the 2015 Cannes Film Festival.

The 40-year-old slapped down 10,000 euros ($11,146) for the item, described as a blue Neoprene flap bag embellished with flowers by The Journal Times, and told auctioneers it was a gift for his mother, Irmelin.

It's for you, sir: Leo DiCaprio made the winning 10,000 euro ($11,146) bid for a Chanel handbag at the glittering Heart Fund Gala auction on Monday at the Cannes Film Festival

An assistant carried the box to where The Wolf Of Wall Street sat in at the sparkling, celebrity laden gala.

Leo had competition for the item, which is so valuable Chanel doesn't even list the price on its website advising potential buyers to contact the upscale fashion house by phone for information.

Paris Hilton, 34, was also bidding at the event at the Nikki Beach pop up restaurant at the Carlton Hotel.

'Paris was great. She bid on many things, and Leo did too,' a source told People. 'Both her and Leo were so active during the entire auction. It was really nice to see.'

So kind: The 40-year-old plans to give the blue Neoprene flap bag embellished with flowers to his mum, Ermelin

Leonardo 'was laughing and enjoying himself with his friends' at the big event, which raised funds to bring heart care to poor children around the world.

This year the bash raised a record 5.1 million euros ($5.7 million) for the Heart Fund.

A lot of that was due to an unnamed donor who pledged 5 million euros ($5.58 million) for a private plane for the organisation to fu doctors and nurses to the world’s most remote areas to perform surgeries and screen children for heart disease.
