Leonardo DiCaprio got into a bidding war with Paris Hilton for a designer handbag last night (18.05.15).
The 'Wolf of Wall Street' star, who is rumoured to be secretly dating Rihanna, reportedly outbid the 34-year-old DJ and secured a blue Chanel Neoprene flap bag embroidered with flowers for €10,000 at the the Heart Fund Gala at the Carlton Hotel in Cannes, France.
The 40-year-old star "bought the bag for his mom," Irmelin Indenbirken, after fending off stiff competition from the former reality TV star and two other bidders, according to the New York Post's Page Six.
Another insider told PEOPLE.com: "Paris was great. She bid on many things, and Leo did too. Both her and Leo were so active during the entire auction. It was really nice to see."
However, the Oscar-nominee lost out on on two other lots at the auction, including a vacation at one of the luxurious Nikki Beach resorts worldwide.
The star-studded gala raised €5.1 million after a mystery donor pledged €5 million to the charity, which aims to bring heart care to poor children.
The money will be used to fund a private plane that will visit some of the world's most remote areas to perform surgeries and screen children for heart disease.
