Lindsay Lohan's mother DINA has hit out at talk show host Jay Leno for mocking the starlet's drink driving arrest on his show. Lohan was due to appear on the Tonight Show just hours after she was detained by police for DUI. Comedian Rob Schneider stood in, dressed as the actress, and he and Leno poked fun at the troubled star in her absence. In an email to Access Hollywood, Dina Lohan has expressed her disappointment with the show. She wrote, "We have a great respect for Jay Leno but we are disappointed in the path he chose to allow a guest to make light of a very serious situation concerning Lindsay. "This is a very personal and private matter and our only concern is to get Lindsay the help that she needs. We will get through this together and it will make our family stronger." Lohan Snr, meanwhile, praised late night talk show host Craig Ferguson for not mentioning Lindsay on his show: "Thank you to Craig Ferguson for not making a mockery of such a serious situation to which teens and young adults are facing across the country! "Our thoughts and prayers go out to all families who have had to see a family member through tough times."
