Make room in bed for Amy Leigh Andrews, Karissa and Kristina Shannon.

Yesterday, we reported that those 19-year old twins were two of the new girlfriends of Playboy founder Hugh Hefner.

But, as anyone who watches The Girls Next Door knows, Hef likes to travel (i.e. have tons of sex with) in threes.

So it's time to meet Andrews, a Playboy Bunny that was named Co-End of the Month by the magazine for October.

Andrews is a 24-year old graduate student from Atlanta. A few weeks ago, following a photo shoot of the blonde model, Hefner said:

“She was testing here this past weekend and she said she’d like to be a girlfriend, too.”

According to her MySpace page, Andrews draws inspiration from... Paris Hilton. The quote that accompanies her profile picture is courtesy of Hilton and reads: "The only rule is don't be boring and dress cute wherever you go. Life is too short to blend in."

And to not have sex with your 82-year old boss!
