Actors Stephen Baldwin and Leif Garrett are among the celebrities volunteering to learn the dangerous sport of rodeo for an upcoming reality series. The pair will join rapper Vanilla Ice and six other stars on the U.S. show, where they'll receive bull riding lessons from expert Ty Murray. The celebrities will take part in ranch tutorials for 10 days, learning how to mount the bull in the chute, take a fall and focus their concentration. Those who make it through the lessons will compete at a Professional Bull Riders event in Nashville, Tennessee.
