She's just being Miley ... on "Two and a Half Men."

Singer-actress-Obama supporter Miley Cyrus will guest star on the Oct. 18 episode of "Two and a Half Men," and CBS has released a first clip of her appearance.

Cyrus plays Missi on "Two and a Half Men," the daughter of a friend of Walden (Ashton Kutcher). In previous press materials for the episode -- like the photo at left -- Cyrus and Kutcher were shown in bed together, but the scene above focues on the origin of Missi's name and not any bedroom antics.

Watch the video above and check out stills from the episode below.
