Finally! After years of speculation, actor Will Ferrell has finally confirmed that he and Red Hot Chili Peppers drummer Chad Smith are indeed the same person. And now Smith has challenged the actor to a drum battle.

Ferrell recently revealed during a Reddit AMA ("Ask Me Anything") that he's not only aware of the rumors that have circulated for years regarding his striking resemblance to the often-shirtless drummer, he actually admitted that he -- or rather, Smith -- has been fooling fans for years.

“It has been acknowledged many times that myself and Chad Smith, drummer for the Red Hot Chili Peppers, share a resemblance to each other,” said Ferrell. “A lot of people think that it’s me playing for the Red Hot Chili Peppers. But that would be an insult to Chad Smith. The truth of the matter is there is no Will Ferrell. Only Chad Smith.”

Ferrell even offered video proof in the form of an Instagram confessional:

But then Smith got in on the action, challenging Ferrell to a drum battle in his own video post. "Stop impersonating me," he says, pointing at the camera. "Drum battle, me and you. I've seen your skills, you don't got 'em. Let's go. Golden cowbell -- winner." You can watch it below.
