Katherine Heigl has no desire to cheat

Katherine Heigl says she has no desire to sleep with anyone other than her husband.

The actress, who is married to Josh Kelley, describes herself as a “serial monogamist”.

“I have no desire to physically hook up with any man other than my husband and have been a serial monogamist from the moment of my first serious relationship at 20. I have never been able to connect with a man sexually without it becoming emotional, without giving a piece of my heart and soul to that connection,” she said.

“I understand that every human being on earth wonders if the grass might be greener in other pastures, but I could never imagine myself really going there or really wanting to. I guess the relationship I’m in is so consuming that the idea of a dalliance with another man sounds exhausting. It’s hard enough to make one connection work. I can’t imagine, even for four days, splitting myself between two!”
