Yogis attending class at Downward Dog studio in Toronto got a surprise visit from Sting earlier this week. The musician, in town for the Police reunion tour, dropped into class a few hours before Monday's gig. "Everyone was quiet for a minute when Sting walked in, and then it just calmed down," says Leigh Anne Dunn, who has practiced yoga at the studio for five years. Has a celebrity ever attended one of your yoga classes? Was it a distraction? Inspiring? Energizing? Annoying?
