After gaining 17lbs for a role in the movie Nine, Fergie realized she really enjoyed putting on the extra pounds.  She told Scotland's Daily Record newspaper:

“It was easy to put it on and it was fun and I loved it, I ate fried foods, everything, and I just didn’t work out at all.

“I didn’t care, didn’t even think about it. It was great.

“It was the longest period of time I had ever done that I think since high school.

“But when I started working out – it was a big deal and then getting back into it. It really took me a while mentally to get back to that routine. So now I have a trainer, which is great, and keeps me motivated.”

Ah wouldn't it be nice if we could all feel that way about gaining a few extra pounds!  And I know Fergie's pain about getting back into the swing of things at the gym, it's always harder to go back.
