Will Ferrell Finally Celebrates His 15th Birthday With An Epic Celebrity Drum-Off

Will Ferrell and his celebrity doppelgänger, Red Hot Chili Peppers drummer Chad Smith, just made good on their promise to deliver another epic drum-off.

After raising raising $500,000 for charity in a drum battle during their "Tonight Show" appearance  last month, they reunited for the "Will Ferrell & Chad Smith's Red Hot Benefit, Comedy + Music & Quinceañera” and upped the ante. 

The event raised funds for Ferrell and Smith's respective charities, Cancer for College and the Silverlake Conservatory of Music , as comedians Nick Offerman, Jim Gaffigan, and Roy Wood Jr. also performed.

But the highlight of the night was the duo's all-out celebrity drum battle. This time they let some star friends, including Tommy Lee , Fred Armisen , Fleetwood Mac’s Mick Fleetwood and, in a surprise twist, a "14-year-old from from Brentwood, California,” do the heavy lifting. 

Thankfully, Funny Or Die captured the night on Facebook Live. 

The charity event hosted on Friday night at the Shrine Auditorium in Los Angeles also doubled as a chance for Ferrell to fulfill his lifelong dream to have quinceañera. No, seriously. For once, he wasn't joking. 

"I have only one great regret in life and it's that I never actually celebrated my quinceañera," Ferrell said in a statement, according to Rolling Stone . "I'd like to think it was just a simple oversight by my mother, but there has been a void inside me for many years. Growing up on the mean streets of Irvine, California, I have vivid memories of all my friends celebrating their quinceañera. Well, on April 29th at the Shrine Auditorium, with Red Hot Chili Peppers and a bunch of other really talented comedians and musicians by my side, we are going to right that wrong, and everyone is invited."

Righting that wrong, of course, meant that Ferrell appeared on stage at one point dressed in a sparkly blue princess gown. 

We could have sworn he wasn't over 14.
