It seems the clown-faced bobsie twins that Hef is getting down with these days have a little bit of a past.

The girls, Karissa (left) and Kristina Shannon (right) seem to have some anger issues. The sisters, both 19, were busted in St. Petersburg, Fla. last January for felony aggravated battery and had to pay restitution to their two victims.

Karissa is the more eviler of the two, also having a misdemeanor battery charge stemming from an incident last year.

Just look at that face - and those brows! (in the mugshot) Bitch looks like a force to be reckoned with.

Hef, you’re slipping buddy. And I bet he knows it too. My guess is the twins, who are probably squealing with joy over the recent publicity they have gotten, will fizzle out faster than they came into the picture.
