When things go downhill in your life, what you really ought to do is spend time in the company of someone who's truly winning. Like Charlie Sheen. If anything, that experience can only make you feel better about your own situation. That's what Lindsay Lohan's doing. The Mean Girls star is said to have planned to spend some time with the Anger Management actor before checking into rehab.

The troubled actress is to spend 90 days in an in-patient facility as part of a plea deal agreed this week relating to charges over a car accident last July and before she begins treatment - which must be before May 2 - she intends to make the most of her time by fitting in both work and pleasure.

A source said: 'Lindsay's pre-rehab plan? A week with Charlie Sheen in LA, then she wants to go to Brazil. I kid you not.'

During her time with her 'Scary Movie 5' co-star - who has repeatedly supported the actress, giving her $100,000 to pay a tax bill and offering to be her mentor - the 26-year-old actress will spend two days shooting a guest appearance on his TV show 'Anger Management'.

Speaking of the role, her lawyer Mark Heller told the New York Post newspaper: 'He's a therapist, and she'll play a patient who falls in love with him.'

Meanwhile, despite claims the 'Liz & Dick' star is romancing City of the Sun musician Avi Snow, Mark insisted there is nothing serious between the pair as she has 'many boyfriends'.

He added: 'Lindsay is a beautiful young woman who has many pursuers and many boyfriends.'

Could this be the cure that poor LiLo need?
