Fat actress Kirstie Alley will battle the pounds in a new TV reality show.

RadarOnline.com confirmed the formerly svelte star is going to showcase her caloric combat on a new A&E show.

"The show will feature Kirstie and her family members," a production insider said.

Kirstie was once a Jenny Craig spokesperson in 2004 and lost 75 pounds by 2006, dazzling Oprah with her new trim look but as The ENQUIRER reported previously Kirstie not only regained all that tonnage but recently entered a fat farm. (SEE REPORTS BELOW)

If she doesn't lose all that weight, experts say, her health may be at risk, resulting in an early death.
