Does Leonardo DiCaprio play the guitar?

Not that we know of, but that didn't stop him from buying one last night.

The Revenant star won a guitar once owned by Bono for $100,000 during the live auction at Sean Penn's annual J/P Haitian Relief Organization gala in Beverly Hills.

That wasn't the only way the DiCaprio chipped in. A package that included lunch with him and Penn as well as a five-night stay at his Palm Springs estate went for a whopping $200,000.

By the end of the night, $7 million was raised for J/P HRO.

The ukulele Madonna played during her surprise performance of "Le Vie en Rose" went for a staggering $300,000 after she promised to "lick" and "kiss" it. (The winning bidder has to wait until Madonna finishes her Rebel Heart tour in March to own it because it's the same one she uses during her concerts.)

Napstar founder Sean Parker paid $100,000 for drum lessons by Metallica's Lars Ulrich.

Anderson Cooper not only emceed the event, but he also donated $50,000 to the organization. Jason Segel and Suki Waterhouse both pledged $10,000.

The fifth annual event ended with a performance by Tom Petty.

The program kicked off just as news hit that Penn had interviewed Mexican drug lord Joaquín "El Chapo" Guzmán Loera for Rolling Stone while he was on the run from law enforcement after escaping from prison.

Penn's face-to-face with the Sinaloa cartel leader, who was captured again on Friday, was organized with the help of Mexican star Kate del Castillo.

Penn declined to do interviews with media last night.
