Richie Sambora returned to rehab last Monday - joining Lindsay Lohan at the Cirque Lodge in Utah. This is the second this year the Bon Jovi guitarist has been to rehab. After his split from then-girlfriend Denise Richards in June, Sambora spent a week at the UCLA Medical Center in LA. At the time, he told NBC's Matt Lauer that he'd decided to go the rehab route because "I was just drinking too much, and I needed to get my life together." The 48 year old reportedly has a private room at Cirque.
