"Saturday Night Live" is relying on an even mix of first timers and old pros to headline the show throughout the month of February, according to a source at the show.

The fun will begin February 8, when Matthew McConaughey and Dixie Chicks are both scheduled to make their debuts. McConaughey's latest film, the romantic comedy "How to Lose a Guy in 10 Days," hits theaters that weekend. Dixie Chicks latest album, "Home," is up for Album of the Year at this year's Grammy awards.

"Alias" star Jennifer Garner is set to take on hosting duties the next weekend, February 15, with musical guest Beck back for a fourth time. Garner co-stars with Ben Affleck in the action film "Daredevil," opening that weekend. Beck's album "Sea Change" is up for Best Alternative Music Album at the Grammys.

The month is slated to end with a bang, as Christopher Walken returns for a sixth time as host, alongside the music of Foo Fighters, Grammy nominated for their rock song "All My Life."

All guests are subject to change until confirmed by NBC.
