Looks like Hef's new gal pals, 19-year-old twins Karissa and Kristina Shannon have some regrettable incidents in their brief pasts.
What ugliness could such lovely ladies have been involved in? You ask...
According to TMZ the twins know how to beat a bitch down:
The twins went out after work with one of their Wing House co-workers, Erica Civello, to a house party. Kristina allegedly started arguing with Erica, and Karissa came up behind her and hit Erica over the head with a bottle of beer and they both "jumped her." Erica suffered a concussion.
Do people not know about TMZ by now? When casting barely legals to be your creepy pretend girlfriends, you've got to be checking their backgrounds
Uh, we meant the crimingal background, not the actual back, but whatever.
