Fergie has embarked on a gruelling workout plan to shift her lady lumps in time for her wedding next week.

After indulging in an all-you-can-eat diet to pile on the pounds for her role in new movie-musical Nine, the Fergalicious star has been snapped exercising at every opportunity in a bid to drop the extra weight.

Fergie - who ties the knot with actor Josh Duhamel on January 10th - has been hitting the streets of L.A. for daily two-hour jogs in the run up to the big day.
