On the outside, it appears that Rob Lowe has had a blessed life; Now, the Brat Pack hunk is finally opening up about the demons that landed him in rehab at the peak of his career.

In his new autobiography, Stories I Only Tell My Friends, the hunky 47-year-old spills the beans on his booze-drenched past, as he partied with high-profile childhood pals such as Charlie Sheen, Emilio Estevez and the late Chris Penn.

The man who was adored by millions reveals how he and Sheen raised hell in the Hamptons when the pair were filming there (Lowe was making Masquerade, while Sheen was filming Wall Street).
