CBS' Crime Scene Investigation has enlisted one of the leads on MTV's Faking It for a familiar role.

Katie Stevens — who stars as Karma on the MTV comedy — has joined the cast of the two-hour series finale, The Hollywood Reporter has learned.

Stevens will play Catherine Willows' (Marg Helgenberger) daughter, Lindsey Willows. The character is now in her early 20s and a CSI Level 1 who experiences her first day on the job. She's an over-caffeinated younger, bubbly version of her mother and — minus a youthful mistake or two — is on her way to a promising career. She nails down a key piece of evidence in the case at the center of the series closer.

American Idol alum Stevens becomes the third actress to portray the character and follows Madison McReynolds (who appeared in nine episodes from 2000-05) and Kay Panabaker (seven episodes, 2006-15).

The two-hour series finale, set for Sept. 27 on CBS, will feature the returns of William Petersen (Gil Grissom) and Helgenberger, who join Ted Danson (D.B. Russell), Jorja Fox (Sara Sidle), Jon Wellner (Henry Andrews), David Berman (David Phillips), Paul Guilfoyle (Jim Brass), Wallace Langham (David Hodges), Elisabeth Harnois (Morgan Brody), Robert David Hall (Dr. Al Robbins), Eric Szmanda (Greg Sanders) and Melinda Clarke (Lady Heather). Both Elisabeth Shue (Julie Finlay) and original star George Eads (Nick Stokes) — who quit the series last season — will not participate.

CSI creator Anthony Zuiker will pen the script for the send-off, with Jerry Bruckheimer, Carol Mendelsohn, Ann Donahue, Jonathan Littman and Petersen set to participate.

Stevens is repped by CAA, Impression Entertainment and Bloom Hergott
