Nick Gruber, the former porn star and on/off boyfriend of Calvin Klein, is out of rehab and ready to turn over a new leaf. In April, Gruber was flown to the Meadows rehab facility in Arizona — on Klein’s G4, no less — after he was arrested for assault and cocaine possession following a fight with a friend. After about a month of treatment, Gruber has a new perspective. He posted (ungrammatically) on Facebook on Monday: “Hey everyone. I just had such amazing learning experience from Rehab. I have leaned so about my self. I am so Thankful that I went. I am a different person. I don’t want to go back to my old self. I want to focus on my future on become a successful person on Education, Work and Bettering my self every day by day. No more partying. Time to be a grown adult. Thanks to rehab and the people who love and care About me. I am now going to aftercare. I want to better my self even more.” Gruber, according to his Facebook status, is headed to California. “On a road trip to LA. Just left Sedona sliding rocks and the Chapel of the holy cross,” he posted on Monday, continuing, “Now going to Flagstaff and Grandcanyon to watch the sunset.” Gruber’s lawyer, Ben Brafman, had no comment.
