Dina Lohan isn’t laughing over Rob Schneider’s drag parody of her drunken daughter Lindsay, who the comedian replaced on Tuesday night’s episode of ‘The Tonight Show with Jay Leno.’

“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,” Dina told Access Hollywood’s Billy Bush in an e-mail Thursday.

“This is a very personal and private matter and our only concern is to get Lindsay the help that she needs,” Dina adds in the e-mail. “We will get through this together and it will make our family stronger.”

“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!” wrote Dina.

She added: “Our thoughts and prayers go out to all families who have had to see a family member through tough times.”
