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

The 49-year-old hunk was known for his partying and womanising 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.

He said: ''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.

He told the Sunday Telegraph newspaper: ''My two sons are the most important things in the world to my wife and I - they are what I build my world around.''
