Lindsay Lohan's father thinks her mother is a bad influence on the starlet.

Michael Lohan, spoke out after the release of a preview clip of Dina Lohan during an interview with Dr. Phil Mcgraw.

In the video Dina can be seen slurring her words and looks disheveled.

Now her ex-husband is saying she has been on the decline for seven years.

He told website Hollyscoop: ''Over the last seven years Dina has come to such a bad place!

''The people she surrounds herself with are no better [than Lindsay's], so what kind of an Example is that?''

Michael has experienced his own public scandals, and is expecting a child with on-again-off-again girlfriend Kate Major after attempting to clean up his act.

He thinks that Dina needs to come clean about her problems for things to get better.

He said: ''[Dina] just needs to be honest with herself and others. Only then will her heart get right and our children will find Peace!

''I haven't seen the full interview yet, but from what I have seen and Dina's comments that [the interview] was 'doctored,' I really think it's sad and I feel sorry for Dina!''

But Lindsay's parent and manager is adamant she was sober during the televised chat.

She told website ''I don't care what it looks like. I'm fine and I don't care what anyone says.

''All people saw was two minutes edited of an hour long interview. Of course they cut it to make it interesting.''
