London: Troubled star Lindsay Lohan is not on board the upcoming season of reality TV show 'Celebrity Big Brother', her representative has said.

The 25-year-old actress was expected to appear on the Channel 5 reality show if the US courts allow her to leave the country but her representative has dismissed the reports, Daily Star reported.

"Lindsay is not doing Big Brother," the representative said.

The actress spent four-and-a-half hours behind bars last month for violating a probation order imposed in 2007 after she was jailed for two counts of drinking and driving.

The show is due to air in January next year.
