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