Cheryl Ladd

Before NBC's Chuck signs off, the spy caper will finally introduce us to Sarah's never-before-seen mother.

Cheryl Ladd, who replaced Farrah Fawcett on the original Charlie's Angels, will play mama Emma in the eighth episode, set to air in January 2012.  There's a reason Emma's been absent from her daughter's life for the past five years — it turns out the two have a "complicated" past.

In addition to Chuck, Cheryl will also appear on CBS's NCIS later this month as a love interest for David McCallum's Ducky.
