Lindsay Lohan's mystery illness

Lindsay Lohan has been admitted to hospital with a mystery illness.

The 'Mean Girls' actress was rushed to a Los Angeles hospital after suffering with fever and staff were said to be worried, at first, she might have meningitis.

Her spokeswoman, Leslie Sloane Zelnick, said: "She was wiped out when she went into the hospital. She's going to stay till they figure out what she has and she starts to feel better.

"She had a 103-degree temperature and they are doing tests on her right now. Her boyfriend Wilmer Valderrama, her mother and sister have all been to visit."

The 18-year-old beauty - currently filming a remake of 'Herbie: Fully Loaded' - was taken to hospital last Thursday after complaining she was feeling ill.

She had been due to film her cameo appearance on hit US sitcom 'That '70s Show' - which boyfriend Wilmer stars in - but she had to cancel at the last minute.

A spokesman for the show said: "We're waiting to see how Lindsay is going to be feeling to see if we can reschedule a time to shoot her scene."
