Fergie is leaving no stone unturned to look perfect on her wedding day.
The stunner, who will walk down the aisle on January 10, is these days busy tightening and toning her body to look gorgeous in her wedding dress.
The crooner was forced to gain weight for her role in the upcoming movie, Nine.
However, now she's trying her level best to shed the extra weight.
"It's hard, I've been working out every day," People quoted Fergie, as saying before her New Year's Eve concert in Las Vegas at The Venetian.
Her pre-wedding 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," she said.
Fergie will be tying the knot with Hollywood actor Josh Duhamel in 2009's first month.
