Ali, Street, Lachey are in 'Stars Earn Stripes'

Former athletes Laila Ali and Picabo Street are among a group of celebrities taking part in NBC's new competition show "Stars Earn Stripes," debuting tonight.

The celebrities, who also include Dean Cain and Nick Lachey, are accompanied by members of the U.S. armed forces and others competing in various challenges for charity.

"This is a great show and everything will go to support these military and police charities," Cain said by phone. "We owe these guys so much. I want to do anything to draw attention to them. Whatever I can do, you can bet I'll do it."
