'Chuck': Sarah's mom is an 'Angel'

cheryl-ladd-gi.jpgA big piece of the puzzle that is Sarah Walker will fall into place on "Chuck" this season: We'll finally meet her mother.

The series has cast former "Charlie's Angels" star Cheryl Ladd as Sarah's ( Yvonne Strahovski) mom, EW reports. She'll appear in episode 8 of "Chuck's" final season, which will likely air in January.

Fans have been hoping that they would finally meet Sarah's mother this season, because that part of Sarah's history has always been murky. The show has flashed back to her childhood with her con-artist dad (played by Gary Cole), but mom has always been absent.

With Ladd coming aboard, it should help fill in some of the things that have made Sarah the way she is. Did she leave Sarah and her dad because of his outside-the-law life, or was there something more at work? This is "Chuck," so we wouldn't bet against the latter.

Ladd was a semi-regular on NBC's "Las Vegas" a few seasons back and starred in Hallmark Channel's movie "Love's Everlasting Courage," which debuted Saturday (Oct. 1). She'll also guest-star on an episode of "NCIS" later this month.
