Fergie is feverishly trying to tone up before her January 10th wedding to Josh Duhamel. Fergie, who is known for her famously sculpted body, had to put on weight for her role in Nine but doesn’t want to look out of shape her in wedding dress.

Fergie told People.com she’s been “working out everyday.” Her workout routine? “A lot of hiking and doing a bunch of sit-ups, working my butt off and just, you know, try to maintain and stay healthy.” 

Fergie performed last night in Las Vegas at The Venetian and rang in the new year with Josh at Lavo.
