Hefty honey KIRSTIE ALLEY is on the loose!

Weeks after dumping 21-year-old boyfriend, hip-hop artist Shancie Boyd, Kirstie Alley is robbing the cradle again! The ENQUIRER caught the 60-year-old former “Fat Actress” locking lips with professional ballroom dancer Ted Volynets – who’s also just 21.

“Kirstie just can’t seem to get enough attention from younger guys these days – and she doesn’t care who knows it,” an insider revealed.

“After dropping a lot of her weight, she looks fantastic and hasn’t seemed this happy in years.”

Before her stint on “Dancing with the Stars,” Kirstie had publicly stated that she hadn’t dated in a decade – and now she’s making up for lost time, say pals.

As The ENQUIRER re­cently reported, Kirstie halted her fling with Shancie after learning he still lives with his mother.

She met Ted through her “DWTS” partner Maksim Chmerkovskiy, and she likes him so much that she’s been stay­ing in New York City, close to his home base, so she can see him more.

“Ted makes Kirstie feel young and vibrant again. Right now, Kirstie’s all about letting the good times roll," the insider divulged.
