Will Ferrell has responded positively to Chad Smith's invitation of a drum battle.

The actor and the Red Hot Chili Peppers sticksman have long been noted for their similar looks and it reached a head recently when the Anchorman star joked that he is actually Smith.

The drummer then responded by inviting Ferrell to a drum battle - something which he has now accepted.

Speaking on Reddit during a chat hosted by Smith, the Step Brothers man said: "Hi, Chad. Will Ferrell here. I saw your video and I graciously accept your invitation to a drum battle. If we can raise $300,000 (£182,000) for Cancer For College I will face off with you in the greatest drum vs. cowbell showdown the world has ever seen. We can do it on stage at a Red Hot Chili Peppers concert or in front of a mutually convenient public library. Your call. Also, would you rather fight a hundred duck sized ducks or one horse sized horse?"

Smith meanwhile added: "I have to comment that I think Mr. Ferrell is a delusional imposter. It seems to me that he has gone off his meds and he needs to seek professional help because I am obviously more talented and handsome than he is. You know, his cowbell work is well-documented, but his drumset skills are nominal based on Step Brothers the film. Other than wiping his testicles on the drums, which of course I give high marks to."
