Fergie hits the gym before wedding

Fergie is spending the time leading up to her wedding working out in the gym.

The Black Eyed Peas singer told People that she is desperate to lose weight ahead of her marriage to Transformers actor Josh Duhamel on January 10.

"It's hard, I've been working out every day," she said, adding that her exercise regime consists of "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".

The popstar earlier revealed that she has had to gain weight for her role in musical Nine.
