‘MY Name is Earl” co-star Jaime Pressly cleans up real good – if this photo from an upcoming “MADtv” sketch is any indication.

Pressly, who plays Earl’s (Jason Lee) trailer-trash ex-wife, Joy (inset), on the hit NBC sitcom, moseys over to Fox to host the Feb. 4 episode of “MADtv.”

In this sketch, titled “My Name is Dubya,” Pressly is gussied-up to play prim-and-proper New York Sen. Hillary Clinton.

In the sketch, Hillary was once the true love of future President George W. Bush (Frank Caliendo) – who, like Earl, is now trying to right all the wrongs from his past.

Pressly, who’s 28 and hails from North Carolina, has gotten her big break on “Earl,” which airs Thursday nights and was just renewed for a second season.

Pressly’s “MADtv” episode airs Saturday, Feb. 4 (11 p.m./Ch. 5).
