Here's Team USA downhill skier Julia Mancuso trying to get America hooked on crack ... and it's working.
The 29-year-old Olympian -- who chalked up a gold medal at the 2006 Olympics in Turin -- threw on one of the lowest plunging catsuits ever for a sexy photo shoot for February edition of GQ.
Mancuso is considered America's best hope for Olympic gold in the speed events -- and she doesn't lack confidence. In fact, she brags on her Twitter page, "I ski better than you."
Hope she's right ...
