Kris Jenner
The Kardashian/Jenner mom is great at doing business and equally great at making her children embarassed. In 2010 she released her book “Kris Jenner and All Things Kardashian,” where she admitted to having an affair when she was married to her husband Robert. Even if her five children knew about the tryst, details about Kris “having sex everywhere” undoubtedly made them uncomfortable.
