From the red carpet to the ladies room.
That's where Lindsey Vonn found herself Monday night at the Council of Fashion Designers of America (CFDA) Awards at Lincoln Center.
Testers from the U.S. Anti-Doping Agency (USADA) surprised the professional skier and escorted her to the bathroom for a urine test. The results were then sent to a lab, though they have not yet been made available.
Both Vonn's agent and the USADA confirmed the random drug testing, reports the Associated Press.
Olympic athletes are required to inform the USADA of their plans at all times, and subject to sporadic, random testing.
