Kirstie Alley packs on 83 pounds

LOS ANGELES, May 6 (UPI) -- U.S. actress Kirstie Alley says she has gained 83 pounds since she stopped being a Jenny Craig spokeswoman in late 2007.

"I started screaming," Alley told People magazine about stepping on the scale for the first time in 15 months.

"It said 228 pounds, which is my highest weight ever," the 58-year-old former "Cheers" star said. "I was so much more disgusting than I thought!"

During her three years as a Jenny Craig spokeswoman, Alley lost 75 pounds and reached her then-target weight of 145 pounds.

After leaving Jenny Craig, however, she stopped working out and went back to eating takeout food and pasta topped with butter, People.com quoted her as saying.

"I fell off the horse," Alley said, adding that she is now determined to start eating better and working with a trainer again in an effort to get down to her goal weight of 128 pounds.

"I'm going to have to work harder than last time," she said. "(But) I'm way excited."
