Legendary Guns n' Roses, Velvet Revolover guitarist Slash was honored Tuesday with his own star on the Hollywood Walk of Fame.  Several of the iconic guitarists closest personal friends were in attendance, including neighbor and longtime buddy Charlie Sheen, who spoke to the crowd gathered in front of the Hard Rock Cafe on Hollywood Blvd.  Sheen was his usual self, delivering several jokes about he and Slash's drug use in the 80s, and also took the opportunity to slam the guitarist's former bandmate, Guns n' Roses frontman Axl Rose.  "It's quite fitting that Slash is getting a star on the very street Axl Rose will one day be sleeping on," Sheen said.  Check out a clip of Sheen's speech at the ceremony below.
