"In the strip club, of all places, which is really weird," Derek told of his cameo to E! at the Rock of Ages premiere in Hollywood. "I was just there visiting, and I walked in and [director] Adam [Shankman] was like, 'Sit down there.'"
"There" was in view of his sister doing pole dance stripper moves. Yeah. "It was just funny because once she started dancing and doing the whole thing, I was like, 'I think I'm going to go now,'" Derek joked.
Weirdly enough, siblings getting a wee bit too close for comfort is the major trend of the year. So … er … congrats, Derek and Julianne!
