Rob Lowe feels "lucky" to have put his wild past behind him.

The 49-year-old hunk was known for his partying and womanizing as a member of the Hollywood "Brat Pack" - also consisting of Charlie Sheen, Emilio Estevez and Andrew McCarthy - in the 1980s but while some of his pals succumbed to their exuberant lifestyles, Rob entered rehab at 26, after a sex tape of himself leaked, and has been sober ever since.

"I am lucky I got through it. A lot of people just don't. You can't drink yourself to death, you can't burn yourself out on drugs, you can't go crazy or let the business eat you up. I definitely enjoyed myself. [But] I have been sober now for 22 years ... 23, in fact. I know that had I not done that, I would never have made it."

The Killing Kennedy star is now happily married to Sheryl Berkhoff - his wife of 22 years - and is a proud family man with two sons, Matthew 20, and 18-year-old John: "My two sons are the most important things in the world to my wife and I - they are what I build my world around."
