Fergie Fergie Fergie's big day is just around the corner.

But after putting on weight for her last film role, the race is now on to lose it.

Fergie's walking down the aisle on the 10th January and wants to be firing on full Fergie-licious cylinders.

But since she piled on the pounds for her movie, Nine, she's found her wedding dress a little tighter than she'd like.

Yet, this super-fit chick knows just what to do to get herself tighter and more toned.

She told People: "It's hard, I've been working out every day."

So what does her all-out workout consist of?

"A lot of hiking and doing a bunch of sit-ups, working my butt off and just, you know, trying to maintain and stay healthy."

Just don't wear yourself out Fergie, save some energy for the day itself.
