Farrah Freaks at Shatner's Roast

The former Charlie's Angels' star appeared to go into meltdown on as she was interviewed with Star Trek actor William Shatner.

The actress looked frazzled with her normally neatly groomed hair unbrushed and mop-like. Her thin figure and the veins protruding from her arms even put her health in question.

Fawcett claims she 'wasn't on anything' during the interview, despite appearing confused and disoriented.

She forgot her lines and later jumped up and down on the stage, ruffling her hair, and holding her head in her hands.

The appearance - as a guest on The Comedy Central Roast of William Shatner - was similar to an infamous 1997 interview she gave to U.S. chat show host David Letterman when her incoherent chatter led to rumours of drug abuse.
