In 2001 Harper started modelling in London at her then-husband's suggestion. She moved to Los Angeles the following year for photo shoots before relocating there. Harper appeared in a few amateur porn videos, her first being with TM Video Productions, before working with Ben Dover in her first professional movie. She signed exclusive contracts with Legend Entertainment and Sin City Video. She was also involved in the day-to-day operations of the LA Direct Models agency alongside her boyfriend Ben English, until they broke up in mid-2004.
Harper has appeared in High Society magazine and Club International magazine several times. In addition, she was the April 2002 Penthouse Pet of the Month, Aziani girl feature, and Hustler's May 2002 covergirl and centerfold.
Harper began working as a feature dancer on the strip club circuit and stated that she received some costumes from Flick Shagwell, who had retired from dancing. She has expressed misgivings about the work, saying "I knew I couldn't dance . . . I have no sense of rhythm."
In late 2006 Harper announced that she and Sin City were parting ways and she was looking to shoot more softcore material while pursuing a college degree inpsychology. To this end she has become a cast member in the Cinemax series "Co-Ed Confidential as "Ophelia", and she played "Christy" alongside Nikki Nova in the Digital Entertainment production "Busty Cops 2." Away from porn, in 2009 she had a starring role in the low budget spoof horror Crustacean.
