Actor Robert Patrick says, "the trash talking is for later when we start grinding the gears and banging the bumper."
Olympic swimmer and 2002 Grand Prix champion Dara Torres says her strategy is to keep her head down, "you're right they're talking smack already but I'm gonna keep quiet and go out there and see what happens."
Besides the celebrity race the Indy car race caps off the Grand Prix weekend with Indy 500 champion Ryan Hunter-Reay competing in this round with other pro drivers.
He says, "this is kind of a homecoming for me. I lived in Dana Point for 7 years and I got engaged here so it means something to me to be here."
The Toyota Grand Prix events take place April 17-19th.
