What's the best way to follow up mushy gushy Valentine's Day? With a double dose of murder, of course. And lucky for soap fans, both Hunter King (Summer Newman, The Young and the Restless) and Lisa Rinna (ex-Billie Reed, Days of our Lives; The Real Housewives of Beverly Hills) will be appearing in an episode of this weekend's back-to-back two-episode season finale of CSI: Crime Scene Investigation.

The actresses will appear in "Under My Skin," which is episode one of the two-episode finale event and follows the CSI team as they investigate a murder with ties to two teenaged kidnapped girls. Rinna guest stars as Tori Nola, the wife of the director of the San Diego crime lab, and Hunter guest stars as Lexi Nolan.

To catch the exciting episode, be sure to tune in to the 15th season finale of CBS' CSI on Sunday, February 15, at 9PM ET/PT.
