Watch: Dwyane Wade, Gabrielle Union team up for Gatorade ad

Miami Heat All-Star guard Dwyane Wade and actress Gabrielle Union, his wife, show off their competitive sides in an ad for Gatorade's new sugar-free drink, Gatorade Zero.

The 30-second spot - one of the couple's first projects together - launched Tuesday.

"I think it's great because we're both in the gym all the time working out," Wade told Charli Penn of ESSENCE. "My wife is an athlete too, and even though I'm looked at as this NBA super athlete, in a couple of months I'm gonna be just an old, a former athlete."
