The outspoken comedienne insists she feels sorry for the `Mean Girls` star - who has been sentenced to 90 days jail for violating her probation for driving under the influence -despite recently branding her "dumb" and a "party skank" and says she is appalled at the conduct of the actress? parents Dina and Michael Lohan.

Joan said: "If I were Lindsay`s parents, I wouldn`t be on television discussing it, I wouldn`t be going on to Joan Rivers for doing a stupid joke on her blog, I would be taking her to rehab and a rehab where you don`t get your nails done.

"I think it is so sad, the road that this girl is going down. It`s appallingly sad? She better get into rehab and better get into it fast.

"Lindsay, I am pleading with you? you`re beautiful, you`re smart, you`re talented. Go to rehab, you`re young! Melissa and I will pay for your rehab!"

Joan also hit out at the actress` ex-girlfriend Samantha Ronson - who blasted the 77-year-old comic for making jokes about her former lover - and urged the DJ to do more to help Lindsay.

She added to US TV show `The Insider`: "I am so sorry for Lindsay Lohan. I am so appalled that these people are coming out of the woodwork upset that I did a joke about her. I think they should worry about Lindsay Lohan.

"I think this ex-girlfriend, this DJ - I thought it was a skinny boy when I first saw the picture - came out doing jokes about me and Melissa. Why not worry about Lindsay Lohan? That girl is going to be dead in 10 years if somebody doesn`t take care of her."

"I suggest that this skanky little girl not worry about the jokes; worry about Lindsay. I find this insane that they are all feeding off of Lindsay. Maybe somebody should take care of Lindsay."

Under the terms of her sentence, Lindsay must enter an in-patient rehabilitation program after her release from prison.

The 24-year-old star is due to begin her prison term on July 20.
