Is she slimming down to fit into a wedding dress?

Fergie has shed more than two stone in 12 weeks in a health and fitness drive in the Swiss Alps for an American TV show to be screened next year with personal trainer Josh Salzmann.

According to a report in the Daily Mirror, 54-year-old Fergie has been on a "strict diet of blended foods and intensive workouts, including daily running and mountain hikes", developed by Salzmann.At a charity lunch in Los Angeles Fergie told reporters, “I went up to the mountains, and I ran every day. That’s how I got fit. I may have lost 30lbs, but I want to help combat global obesity. I want to really get into America and support young children who need to be educated about the future.”
