Rocker Richie Sambora has joined Lindsay Lohan at a rehab facility in Utah.

According to reports, the Bon Jovi guitarist has checked into a private room at the Cirque Lodge, where Lohan is currently receiving treatment.

Sambora admitted to battling with alcoholism in June after a short detox stint at the UCLA Medical Centre, saying: "I was just drinking too much and I needed to get my life together... It's been a rough year. I'm still in therapy and stuff like that, but it's good. I'm great. I feel fine."

The 48-year-old began drinking heavily after a series of blows including splitting with wife Heather Locklear and girlfriend Denise Richards.
