Kristen Klessig is an ex-girlfriend of Youtuber Jack Douglass. She is 25 years old, and works as a bar waitress part-time. She lived in Maryland while Jack lived in California. They maintained a well-rounded long distance relationship before breaking up in late 2012.
She was featured in many Jacksfilms videos, most frequently at the end of videos. Usually, Jack would introduce himself and when Kristen would try to do so, he would interrupt her. It was stated in a video named "We Broke Up" that they broke up due to her being on the east coast and he on the west coast, with neither one willing to move.
