She is part of the Shannon Twins. Kristina Shannon is an American glamour model, nude model, actress and porn star. She and her twin sister Karissa Shannon were Playboy Playmates in 2009. In 2008 Kristina and Karissa moved into the Playboy Mansion as two of Hugh Hefner’s new girlfriends. They began appearing on the reality series The Girls Next Door along with Crystal Harris. Kristina appeared as Miss August 2009 along with Karissa as Miss July in a combined “summer issue” of Playboy magazine. Unlike previous centerfold twins, they earned consecutive months as Playmates, but shared a single centerfold. When they appeared in Playboy they still had their natural B-cup breasts, but since have had several augmentations. By January 2010 the twins moved out of the mansion after breaking up with Hefner and moved to the Playmate House. They were originally planned to head a spinoff of The Girls Next Door titled The Girls Next Door: The Bunny House, but they were asked to move out after Hefner learned they had boyfriends. In 2012, Kristina was filmed by paparazzi while on a date with Ida Ljungqvist. She most appears on projects with Karissa. Their first acting job was in a small part of Somewhere. In 2012 they appeared on Celebrity Big Brother in the UK and finished fifth.
