Kirstie Alley Takes Heat for Weighty Scene | Kirstie Alley
Not everybody is getting their jollies from Kirstie Alley's new Showtime comedy, Fat Actress, PEOPLE reports.

The National Eating Disorders Association is unhappy with a scene from the March 7 episode in which a diet coach suggests that Alley induce vomiting to help lose weight. Says the organization's president, Doug Bunnell: "The show reinforces the myth that eating disorders are faddish behaviors rather than serious illnesses."

Alley, 50, hasn't responded, but a Showtime rep says the show "is fictitious. It is in no way intended to ridicule those who suffer from eating disorders."

But weight, there's more: Alley has some celebrity detractors as well. In a poem posted on her online blog, Rosie O'Donnell, who turns 43 next Monday, openly scoffs at Alley's claim that she topped out at just over 200 lbs. The former talk show host challenges Alley to come clean about her true weight, but Alley would not comment about O'Donnell's allegation.

Rosie's poem (from "Fat Celebs," posted on her blog):

earlier this evening
kirstie alley told matt lauer that her fattest was 201
I almost choked on my yodel
I am 220
fess up kirstie – 201 my ass
i started to fume

Alley's response to Rosie's comments? "When a person publicly and inexplicably attacks another's integrity, honesty, religion and character all in one swoop, it's a little hard to comprehend the motive," she said in a statement. "I'm going to chalk it up to 'lack of cool hair extensions.'"
