Curvy beauty KATE UPTON warned to stay away from pas de deux ‘em and leave ‘em MAKSlM!

 “DANCING with the Stars” pro Maksim Chmerkovskiy wants to waltz down the aisle with gorgeous model girlfriend Kate Upton, but her parents are begging her to cha-cha-cha the other way!

Kate’s dad and mom, Jeff and Shelley Upton, see little to love about their daughter’s new beau, say sources.

“They’re not happy she‘s seeing Maksim,” a friend reveals. “His reputation as a womanizer pre­cedes him, and they believe she’s too young to get involved with a guy like this.”

Maks, 33, and Kate, 21, got together in the spring after being introduced by mutual friends.

But what many believed would be just a fling has turned into a full-blown romance. Kate was recently spotted apartment hunting in New York City, where Maks owns dance studios.

“Maks is a lot older than Kate, and he’s got this reputation as a love ’em and leave ’em kind of guy,” the friend said.

“But Kate sees something in Maks that other people, including her parents, do not.

"Maks has heard from Kate about her parents’ reservations, but he’s trying to get beyond that.

"He knows he has a playboy reputation, but he says Kate is the girl he wants to marry – and he’s determined to make it happen.”
