Season 10 of "Two and a Half Men" is getting a little more star power. British comedian and former Mr. Katy Perry, Russell Brand, was roaming the CBS lot and ended up sitting serving Ashton Kutcher some dinner...on camera! reports that Brand was initially on the CBS lot Wednesday for an interview. Producers put the comedian into a  go-cart, but it turns that go-carts aren't really his thing. After railing the vehicle into a wall a couple times, Brand decided to walk off his driving snafu,  and ended up running into Ashton Kutcher!

According to Ok! magazine, Kutcher, who has taken on the role of Walden since Charlie Sheen's departure, was taking a break from filming "Two and a Half Men" when he asked the British star to make a surprise guest appearance on the sitcom. The show was in the middle of filming a restaurant scene, and according to the magazine, Brand stepped in for a role as a waiter. 

"No one would be in the least bit surprised if Ashton asks Russell to make more regular appearances," a source on set told Ok! "He thinks Russell is hilarious, and a real natural!"

Russell Brand won't be the only celebrity making their way onto "Two and a Half Men" this season. Former Disney star Miley Cyrus will be making her way on screen as a Missi, an "old family friend of Walden's who comes to visit for a week and develops a relationship with Jake [Angus T. Jones] when he comes home from the Army."

Also guest starring in season 10 is Michael Bolton and "True Blood" star Brit Morgan.

Season 10 of "Two and a Half Men" premieres on CBS on Thursday, Sept. 27 at 8:30 p.m.
