FergieFergie has said she’s working out almost constantly since setting her wedding date.

The usually svelte Black Eyed Peas star was forced to gain weight for her recent role in upcoming film Nine - but wants to lose the excess pounds to look her best for her wedding to Josh Duhamel next week.

She told People magazine: “It’s hard, I’ve been working out every day.

“[I’ve been doing] 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 and Josh began dating in September 2004 and are set to marry in Los Angeles a week tomorrow. The couple rung in the New Year in Las Vegas, with Fergie playing a gig at the Venetian.
