TV funnygirl Judy Greer has signed on for the revamped “Two and a Half Men.”

The actress will play Ashton Kutcher’s ex-wife and the source of his amazing depression that causes Kutcher’s character, an Internet billionaire, to buy Charlie Harper’s (Charlie Sheen) beach house and ask Alan (Jon Cryer) and Jake (Angus T. Jones) to keep living there, with him, to keep him company.

Greer, 36, is an “Arrested Development” alum and we really liked her on the short-lived CBS comedy “Mad Love.”

Greer actually appeared previously as a character named Myra who slept with Charlie in two episodes in 2007.

The new season of “Two and a Half Men” premieres at 9 p.m. on September 19.
