Fergie, the rocking popstar who's known as much for her smokin' body as her successful singing career, is pursuing a new career ambition: Acting. And you know what actors tend to do -- they slim down or bulk up for various roles. It's the latter for Fergie -- the gorgeous singer is in the process of gaining weight for the upcoming movie musical Nine.

According to Fergie, "I've actually gained 10 lbs! No, really - for the film, 'Nine'. Actually, 13 to be exact. I ate everything! Fish and chips. Everything fried - things I don't normally eat." But she's also looking forward to losing the weight in time for her wedding to Josh Duhamel, adding, "I have to give the bad food up now! So, yeah - I'm in that phase! Back to diet designs - my food delivery service!"

Gaining weight is always the easy part, huh? Good luck to her on the weight loss, though I don't think she needs it.
