Lindsay Lohan not suffering from bipolar disorder

London: Lindsay Lohan`s lawyers have rubbished reports that she is suffering from a bipolar disorder.

The "Mean Girls" star was released from jail Monday after serving just 13 days of a three-month prison sentence relating to a 2007 Driving Under Influence arrest. She headed to a rehab clinic as soon as she was freed, and will spend 90 days at the centre dealing with her personal problems. Reports said Lohan will be treated for bipolar disorder, a psychological condition which induces mood swings, and also needs help for an addiction to methamphetamine. However, Lohan`s attorney Shawn Chapman Holley is adamant the rumours are not true, reports dailystar.co.uk. "I have never seen any psych (psychiatric) report concerning Ms. Lohan which references a `bi-polar` diagnosis or an addiction to `methamphetamine`. I think this is a total fabrication," Lohan added.
