Dr. Phil

The 26-year-old 'Liz & Dick' actress took to her mother Dina Lohan's defence following her shambolic interview with the US chat host earlier this month.

The troubled starlet posted a series of bitter tweets about the TV psychologist on Saturday (29.09.12), most of which she later deleted.

She wrote: "@DrPhil You should be ashamed of yourself. What kind of man takes advantage of a woman @her most vulnerable state? YOU are the fraud."

Dina - who has been called "the worst mother in America" - was slammed by Dr. Phil as a "phony and inauthentic" for appearing intoxicated and making rude gestures during their recent interview.

Up until this weekend Lindsay had not commented on her mother's disastrous appearance, during which Dina lashed out at critics for condemning her parenting skills because of her high profile daughter's numerous stints in jail and rehab.

Lindsay also retweeted a message from a fan on Saturday that said: "ur mom is strong like u, Dr.Phil is an evil guy. Focus on your work linds (sic)".

After deleting the tweets, she wrote: "My last tweet was referencing my amazing, beautiful, talented, strong mother."

Dina also simply responded "karma" to a person who tweeted Lindsay a message saying: "It was painfully clear that @dinalohan was uncomfortable and he exploited her insecurities shamefully!"

Dina has repeatedly claimed her erratic demeanour during her interview with Dr. Phil was because she was so upset and not drunk.
