Crystal Harris is one of Hugh Hefner's girlfriends that star on E! Entertainment's reality series, "The Girls Next Door," beginning with season 6. Crystal Harris is from San Diego, California. Crystal Harris is 22 years old.

Crystal Harris appeared in a series of topless and semi-nude photos as a Coed of the Week on Playboy.com in late October 2008 under the name of "Crystal Carter." When Crystal Harris later went to a Halloween party at the Playboy mansion, Hugh Hefner blew her a kiss, but she was so nervous that she kept walking. It took Crystal Harris's friend to wave him down. Hef then invited Crystal Harris to stay the night and through the weekend. In November 2008, Hef invited Crystal Harris to move in.

Crystal Harris is a psychology major at San Diego State University. Crystal Harris loves Disney movies, seafood, and virgin piña coladas. Crystal Harris enjoys rap, hip hop, country, and easy listening music.

Crystal Harris grew up in England and most of her relatives still live there. Crystal Harris has two sisters, two nieces and one nephew.

Crystal Harris's measurements are 34-25-34.

Karissa and Kristina Shannon are 19 and list on their myspace page that they are Florida natives. That explains their love of posing topless, in a thong on the beach. The Shannon twins are thrilled to move to California to live in the Playboy mansion and have made themselves right at home, even sharing a bathroom with Holly Madison, Hef’s former number one girl.

Karissa and Kristina Shannon have posed for semi nude photos already, as you can see below. But many people are dying to see the Shannon twins nude. They posed nude for the April 2008 issue, and they are expected to make another Playboy pictorial around December. Hef won’t wait too long to show off his sexy twin girlfriends. We are unsure of the twins measurements, but I am sure all of that including cup size will be revealed in time.

Said to be joining the twins as Hef’s third girlfriend is Amy Leigh Andrews. She is a college senior from Georgia and has already posed for Playboy. Amy Leigh Andrews has much bigger boobs than the Shannon twins, and I imagine that may change with time.
