Lisa Edelstein takes it almost all off in part one of a two-part "House" finale.

LISA EDELSTEIN, who plays Dr. Lisa Cuddy on "House," will be fulfilling a fantasy on the first half of the doctor drama's two-part finale, beginning Monday night at 9 p.m. on FOX. In "House's Head -- Part 1," House (HUGH LAURIE) is in a bus accident and loses four hours of his memory. As he tries to piece the missing time together, he enters the world of fantasy.

For Lisa's character's fantasy, House decides to dress her up in a school-girl costume, but he takes it one step further when he has her strip. To make it work, Lisa called SHEILA KELLEY, who has a company called The S Factor, a workout program based on striptease and pole dancing classes to increase fitness.

"She did a movie a long time ago about strippers and realized stripping was a great way to stay in shape and also a great way for women to kind of explore their sexual power," the TV doc explains. "I went to her and she helped me choreograph this routine. I didn't need it for the exercise, because I would show up there after doing two hours of yoga. But in terms of learning about how to be sexy without doing it for somebody else, that is the trick. You stand within your own skin and your own power, you do it for your own enjoyment."

As for Cuddy's relationship with House, which has yet to be fulfilled except in viewers' fantasy, Lisa says: "I think that she very much loves House. She, also, lives vicariously through him because she is a very smart woman who is very successful as a doctor and has a great job and a wonderful position, but she also has less and less to do with the actual practice of medicine as the years have gone by. She is excited by what he does and how he does it, and [is] deeply frustrated by him at the same time. As all intense people are, [he is] incredibly interesting and compelling and she falls victim to that."

"House" airs Monday nights at 9 p.m. on FOX.
