Exclusive: Rachael Leigh Cook Latest Psych Major

I've seen Shawn Spencer's future, and it looks crowded. Not only is James Roday's faux soothsayer getting a visit from his shrinky-dink mama on Psych this season, but one of his exes is coming out of the woodwork, too.Sources confirm to me exclusively that ex-Pussycat Rachael Leigh Cook has signed on to play a high school crush of Shawn's in at least one episode. The two reconnect at their 13-year class reunion and, well, even a pretend seer can predict what happens next.Cook's scheduled to appear in the second episode of the upcoming third season, which kicks off on July 18 (aka not soon enough)!Related:• Psych Finds Shawn's Mother... and It's Cybill Shepherd!
