A day after Lindsay Lohan was sentenced to 90 days behind bars and 90 days in rehab for violating her probation, a source tells "The rehab and jail is unjust. She's so upset."

And so are her parents.

In a statement to AOL's Popeater, the actress' mother Dina said: "This is so not fair to do to my child."

Even before her harsh sentence Tuesday, Lindsay's estranged father Michael declared that he was against his daughter, 24, going to jail and that intense rehab would benefit her more.

On Larry King Live Tuesday night, he said he was in "dismay. But at the same time, [I feel a] little satisfaction that she’s going to a rehab. But the last thing in the world I wanted was for my daughter to go to jail." See the top 10 habits that ruin your appearance.

Though Lindsay denies his claims that she is addicted to prescription drugs, Michael told Larry King: "This girl needs a rehab, she needs help. [Dr. Drew] wanted to help her; he offered to help her a long time ago. If Lindsay’s lawyer and Lindsay would have just listened to us, she would have been in a rehab, she would have been on a way to being clean and sober and have her life back. Instead, she got jail and rehab."
