A spokesman for Bon Jovi said: "Richie Sambora has entered an undisclosed
treatment facility in Los Angeles.

"He asks that you respect his and his family's privacy at this time."
Sambora split from actress Denise Richards in March after dating for almost
a year.

The 47-year-old rocker's divorce from Heather Locklear was finalized in
April and then tragically his father died of lung cancer on April 21.

A source said: "Richie has had a terrible year.

"I think this was a culmination of all these things and finally he realised
he needed to take care of himself. He'd put off everything for so long
taking care of everyone else it was just time to stop and deal with his
issues."
