Rob Lowe says he stopped being unfaithful by becoming sober.
While Lowe has enjoyed success on both the big and small screen during his career, ne hit the headlines in the eighties and nineties for all of the wrong reasons.
Lowe suffered from alcohol and sex addictions, both of which led to him entering rehab in the late 1990s.
But becoming sober has really helped his relationship with his wife Sheryl Berkoff.
Speaking to Haute Living magazine, the actor said: "I had met my now wife, Sheryl, and was attempting my first try at monogamy, which was not really in my nature at the time, and I wasn't able to do it.
"It made me examine how I was living."
Lowe and Berkoff married in 1991 and have two sons together, who were born in 1993 and 1995.
Lowe continues to mix his TV and film work, and returned to the big screen earlier this month in Sex Tape alongside Cameron Diaz.
He has also completed work on Pocket Listing and is currently filming new movie Monster Trucks.
