The trio, along with other famous faces including actress Kim Coates and Mexican star Kate del Castillo, has signed up for the Toyota Celebrity/Pro Race on 14 April (12).
Chiefs at the car firm donate $5,000 (£3,125) on behalf of each participant to Racing for Kids, an organisation which uses motorsports to raise awareness of funding the health care needs of children, while the same amount will also be gifted to the winner's favoured charity.
Les Unger, Toyota's national motorsports manager, says, "It's been astonishing to see how many entertainers and sports personalities have been transformed by the Toyota Pro/Celebrity Race - not just by the event itself, but by the fact that it benefits chronically ill children.
"I have yet to meet a participant who hasn't been appreciative and sincerely affected by the children's hospital visit that we organise ahead of race day."
Actor William Fichtner won last year's (11) race.
