Andrew McCarthy in 'Gossip Girl' spinoff

Actor set to play Lily's father opposite Brittany Snow

Lily Rhodes' family is coming into focus.

Andrew McCarthy has joined the "Gossip Girl" spinoff, playing Lily's father, Rick Rodes, a music company exec.

In other CW pilot castings, Tim Matheson has been tapped for the DC-set "Body Politic."

The WBTV-produced "Gossip Girl" spinoff chronicles Lily's (Brittany Snow) wild teen years in 1980s Los Angeles.

McCarthy joins Snow and Krysten Ritter, who plays Lily's sister Carol Rodes.

Co-starring on a show set in the '80s is fitting for McCarthy, who was a big '80s movie star, appearing in such features as "St. Elmo's Fire," "Pretty in Pink" and "Less Than Zero."

McCarthy, who most recently co-starred on NBC's "Lipstick Jungle," is repped by the Glick Agency and One Entertainment.

CBS Par's "Politic" evolves around young staffers in Washington. Matheson will play a charming, JFK-type senator.
