Lindsay Lohan is so desperate to clean up her tarnished image, the teen singer has been prescribed anti-smoking pills in a bid to curb her nicotine addiction.

The RUMORS singer, who has endured a battering from the press in recent weeks for speculated drink and drug problems, has been persuaded to seek help for a smoking addiction by her mother DINA.

And she hopes her daughter will have kicked the cigarette habit soon, according to gossip site The Scoop.

She says, "Lindsay smokes under a pack a day. She's addicted.

"The doctor put her on an anti-smoking pill. God willing, it will work within a month."

It is the second dose of medication the teen star is undergoing after a severe New Year (06) asthma attack forced Lohan to take pills to control her breathing difficulties.

Her mum says, "Lindsay's on Advair (asthma medication). She can't be around dogs and cats and certain foods.

"And when you're 19, you don't deal with that. I'm her mother and I tell her, 'You have to stick to it.'"
