Rapper-musician Vanilla Ice and actor Stephen Baldwin were among those in Nashville over the weekend to tape an episode of CMT's new series, Ty Murray's Celebrity Bull Riding Challenge. The taping coincided with the Professional Bull Riders' Jack Daniel's Invitational which took place Saturday and Sunday (June 16-17) at the Sommet Center. Others intending to make the eight-second ride included former NFL player Rocket (Raghib) Ismail, Moto X rider Kenny Bartram, actor "Nitro" Dan Clark (American Gladiators), Survivor's Jonny (Dalton) Fairplay, UFC fighter Josh Haynes and actor Francesco Quinn (Platoon, 24). The participants trained at Murray's ranch in Stephenville, Texas, before the competition in Nashville. The series is scheduled to premiere Aug. 10.
