Los Angels: Actress Katherine Heigl says she has never thought of cheating on husband Josh Kelley.
The "One for the Money" actress says she will never get intimate with another man because she needs to have an "emotional" connection.
"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," showbizspy.com quoted the 33-year-old as saying.
"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," she added.
