Leonardo DiCaprio will be spending a day with former President Bill Clinton after bidding big for the opportunity at Sean Penn's charity bash in Los Angeles on Saturday.

The "Titanic" star was a guest at the 2013 Sean Penn and Friends Help Haiti Home Gala at the Montage Hotel to raise money and awareness for the Oscar-winning actor's J/P Haiti Relief Organization, which he set up in the aftermath of the country's devastating 2010 earthquake.

The event featured a special auction and DiCaprio was one of the main bidders for the chance to spend some one-on-one time with Clinton, offering up $100,000 for the honor.

He was promptly outbid, but the lot rocketed up to $400,000 after the Hollywood hunk proposed the two rival bidders join forces and put their funds together to turn the day out for two into a party of four.

DiCaprio also bid for an Explore Bhutan vacation package - but he lost out on that lot to Giorgio Armani's niece, Roberta, who paid $240,000 for the holiday prize.

Other celebrities who showed their support to the cause included Julia Roberts, Richard Gere, Mel Gibson, Daniel Craig and Reese Witherspoon, who each paid between $2,500 and $5,000 for a seat at the gala.

The event raised a total of $2.25 million for Penn's charity.
