Karen Marley says, "During our time together, it's the wife who is the other woman."

Karen Marley claims she is a serial mistress who says she has slept with over 50 married men and adds that she believes the wives are 'the other woman' in her relationships.

She also says she has never broken up a marriage and the woman from the UK (pictured above) brags up her conquests to the Dr. Drew show.

"I have never and would never break up a marriage, simply because I don't particularly want the man," the 45-year-old told Drew Pinsky and relationship expert Simone Bienne.

"I dont particularly want somebody on my doorstep with a suitcase, saying 'I left my wife.' I would be mortified if that happened, because that is not why I started this for."

The Christian Post reveals Marley's mistress lifestyle is facilitated by U.K. website IllicitEncounters.com, a place where married people search for others they can have affairs with.

The report notes that women may join for free, but men must pay $215 a month for the service. Marley does her part though, she said- by being the "perfect mistress."

She earlier said she thought wives were the other women when she is busy having sex with their husbands.

"I get the good bits of married men," Marley told the Daily Mail earlier this month.

"During our time together, it’s the wife who is the other woman."
