Miley Cyrus' TV role is a definite! After a couple weeks of speculation, former Disney star Miley Cyrus has been confirmed as a guest star on the upcoming 10th season of "Two and a Half Men."

Previously reported by an inside source to E! News that the singer and actress was in negotiations to be in "at least several episodes" of the hit CBS show, the network and her reps are now confirming it.

According to Deadline, Cyrus, 19, will be starring in two episodes of "Two and a Half Men" as Missi. A press release confirmed some background information on Missi, stating that she is "an old family friend of Walden's [Ashton Kutcher] who comes to visit for a week and develops a relationship with Jake [Angus T. Jones] when he comes home from the Army."

E! News previously revealed that Cyrus' character will have sex appeal and a sense of humor that catches Jake's attention.

While fans of Cyus and "Two and a Half Men" may be prepping for a hilarious guest spot, one of the stars of the show isn't even aware of the famous guest star...let alone that she's going to be a love interest for him.

Jones, 18, revealed to E! News at the Republican National Convention in Tampa that he had no idea Miley Cyrus would be guest starring as his onscreen love interest.

"Honestly, they don't tell me anything about what the future shows are going to be," he explained of Cryus' guest stint. "But if that's what's going to happen it will be cool. I've met her a few times before and it would be fun to work with her."

As for the "relationship" part of the guest spot teased in the press release, Jones revealed "I'm on a need-to-know basis."

Whether Cyrus will be debuting her new short platinum blonde hair cut in the episodes or wearing a wig is a mystery, former "Two and a Half Men" Charlie Sheen is definitely a fan of the highly talked about hair transformation.

Us Magazine reports that Cyrus and Sheen recently took to Twitter to compliment each other.

Cyrus recently posted that Charlie Sheen "IS THE [bomb icon], while the "Anger Management star replied back, "Idk, w/that new haircut Miles...You're the [bomb icon]. Come watch the show at my place! XO."

Hopefully Sheen won't hold Cyrus' guest spot on his former show against her.
