Mama June -- I'm a Strip Club Superstar Now!

Mama June's making stacks o' cash from a Florida strip club -- and in related news ... there's a polar vortex pushing through hell.

A rep for June tells TMZ the "Honey Boo Boo" matriarch has a signed deal to appear later this month at Crazy Horse Gentlemen's Club in Pompano Beach -- but before you start booking flights ... we're told June's keeping her clothes on.

June will pocket $5,500 for the meet and greet with fans, and get VIP treatment -- including first class airfare and deluxe hotel accommodations.

Although she won't be in her birthday suit ... there's a chance June might hop onstage to show off her new figure. She's lost 45 pounds!
