EXCLUSIVE: Kimberly Williams-Paisley has joined the cast of the Fox fourquel Alvin And The Chipmunks: The Road Chip. The animated/live-action pic sees our rodent heroes hit the road for NYC. Seems a series of Alvin and the Chipmunksmisunderstandings has led Alvin (Justin Long), Simon (Matthew Gray Gubler) and Theodore (Jesse McCartney) to believe that Dave (Jason Lee) is going to propose to his new girlfriend in the Big Apple and dump them. They have three days to stop the madness. Walt Becker will direct the pic from a script by Randi Mayem Singer. Ross Bagdasarian and Janice Marmen are producing, with Karen Rosenfelt as executive producer. Road Chip is set to gnaw into multiplexes December 23.

Williams-Paisley co-starred on According To Jim and her recent TV credits include runs on Two And A Half Men and Nashville. She was on the big screen in last year’s Ask Me Anything and next stars in the features Eden Court and Say The Sinner’s Prayer. She is repped by Gersh Agency and Link Entertainment.
