Lindsay Lohan has blasted a celebrity doctor for claiming she is not sober. Dr. Drew Pinsky - who hosts reality TV show 'Celebrity Rehab with Dr. Drew' which treats famous people battling addictions - claimed in an interview Lindsay will not resolve her personal issues until she hurts herself, prompting the 'Mean Girls' actress to question his ethics.

She wrote on her Twitter page: "I thought REAL doctors talked to patients in offices behind closed doors. Am I wrong? Hmmmmm. I think NOT. Yay!"

Rocker and front man Steven Tyler has reportedly checked himself into a rehab center in Pasadena.

Tyler, 60, checked himself into Las Encinas Hospital drug rehabilitation clinic. This is the same clinic where Dr. Drew Pinsky practices and where VH1's reality show "Celebrity Rehab" was filmed.
