Kendra Wilkinson Fuels Divorce Rumors and Rift with Playboy

A rep for Kendra tells TMZ ... she wasn't planning on going out and was dragged by a friend to the party. Everything is fine with her and Hef ... and Hank as well. We're told she ended up going to the Playboy Mansion party after the Maxim party.

Kendra Wilkinson did little to squash divorce rumors Saturday night, and in the process she started a new one.

Kendra arrived sans hubby Hank Baskett, fueling fresh rumors about an impending divorce.

Maybe even more interesting ... Kendra chose the Maxim Halloween Party over the Playboy party down the road. Kendra, who was a Playboy centerfold, always showed at Hef's Halloween party, so her choice this year suggests all isn't well with them.

A skeleton with bad blood ... interesting.
