Bo Derek

Bo Derek will guest-star in the fifth and final season of NBC's Chuck, TVGuide.com has confirmed.

The'80s sex symbol — who still looks great from where we sit — will portray herself in this season's 10th episode. Her appearance will reveal shocking secrets as well  feature a forbidden romance with one of the characters. (We vote for Jeffster. Yes, both of them.) The news was first reported by The Hollywood Reporter.
