Lindsay Lohan's estranged father Michael continues to reach out to his troubled daughter via the press, this time comparing her to Elvis.

The convicted fraudster-turned-celebrity boxer now says he fears the actress will end up like other prematurely departed stars if she doesn't get help for her "prescription drug abuse" (that's Michael talking there.)

"She needs long-term rehab," he tells UK magazine Grazia. "I fear the worst. Look at Elvis, Anna Nicole Smith, Heath Ledger - who was a close friend of hers.

"It could be a year, a month, a week - who knows? She has a plethora of medicine you can't mix and can't drink with."

These latest comments are likely to alienate Lindsay further.

As we reported, the actress recently said she was “hurt” by what she called her father's "excessive lies."
