Kirstie Alley has re-signed with diet company Jenny Craig.

The voluptuous actress is set to become the weight-loss brand's spokeswoman for the second time, seven years after parting ways with them.

Kirstie shed a whopping 75lbs in 2004 when she first used Jenny Craig meals and nutrition supplements and stayed slim for three years, but did gain weight when she stopped working with the company in 2007.

The former 'Cheers' star is now determined to beat the bulge after putting on 30lbs over the last six months, and hopes Jenny Craig will help her find her discipline again.

She told People magazine: ''I was good for awhile and then I wasn't good, and the weight crept up. Like I say in the ad, I'm not circus fat. I didn't hugely screw up. I didn't gain 75. I gained 30.''

She added: ''I love that you have a consultant. It's like being an athlete. No athlete is going to do well without having a coach. We have to equate that to life.

''Without a coach helping us along the way, I don't think someone can make it for the long haul.''

Kirstie will be tucking into calorie-conscious Jenny Craig meals as well as supplements from her own Organic Liaison line, which will be available to the public from Jenny Craig centres.

The comedienne's new deal could be part of her master plan to find a new man in 2014.

She recently confessed she was hoping for love as she hasn't had a serious boyfriend in over a decade.
