Kristina and Karissa finishes 5th place in Celebrity Big Brother 2012.

Glamour girl twins Kristina and Karissa Shannon are American glamour models who are best known for their roles as Playboy Playmates.

After moving into the Playboy Mansion in 2008, the gorgeous twins became two of Hugh Hefner’s three new girlfriends. This catapulted them into fame and they began appearing on the hit US reality television series, The Girls Next Door.

They managed to last 23 days in the house under the watchful eye of Big Brother and the British public.

The twins will be best remembered for their high profile opinions about themselves as well as sparking many a few arguments with other housemates.

One of their most memorable moments took place in the final week when they came to blows with Denise following an incident during a girly night. Denise playfully tugged on Karissa‘s Pyjama trousers to pull them down, much to Karissa‘s dismay which resulted in a full-scale row amongst Denise, the twins, Nicola and Frankie.

Overall, the twins proved that they were more than doubly prepared for all the challenges of House life, teaching some of the others that you shouldn’t mess with them because there’s “two of them.”

Upon leaving Kristina and Karissa told Brian Dowling “We didn’t know what was going to happen last week so we’re happy we’re here now. Everybody won”.
