McDreamy to race in Homestead grand prix

The doctor is in at the Homestead-Miami Speedway.

Actor Patrick Dempsey -- also known as Dr. Derek Shepherd on ABC's "Grey's Anatomy" -- will take part in the 250-mile, 109-lap Gainsco Grand Prix of Miami. It's the second race of the 2008 Grand-Am Rolex-Sports Car Series.

Dempsey and co-driver Joe Foster will be behind the wheel of a specially painted No. 40 Hyper Sport Mazda RX-8.

Dempsey came in sixth in the Homestead race last year.
