Charlie Sheen revealed the reason behind his decision to go under the knife. In his newly released memoir, The Book of Sheen, out Tuesday, September, 9, Sheen, 60, opened up about his decision to get liposuction. While reflecting on a trip to Toronto, he shared that he had hired a sex worker to end his "celibacy streak." "If any of us look back on the moments that defined us or influenced major decisions, they tend to include a foreshadowing detail, others right near the surface or buried deeper for latent discovery," he wrote.
