It's been a tough year for Bon Jovi guitarist, Richie Sambora. In April, his divorce was finalized from Heather Locklear and his father died of lung cancer. Richie also recently broke up with girlfriend of a year, Denise Richards. Now the 47-year-old musician has entered an LA treatment facility for an undisclosed problem. "He asks that you respect he and his family's privacy at this time," said his spokesperson. At a taping of MTV Unplugged this week with Bon Jovi, Richie was apparently too inebriated to play along - and his mic was turned off to cover his mistakes, according to Perez Hilton. Good luck, Richie!
