Irish heart-throb Colin Farrell was confronted during filming for The Tonight Show With Jay Leno on Thursday by the woman who last year accused the Alexander actor of stalking her.
Dessarae Bradford alleged that Farrell bombarded her with explicit phone calls and text messages, but she subsequently failed a lie detector test on a US TV show.
When Bradford jumped out of the audience and approached Farrell, many people thought it was a comedy sketch. When it became clear Bradford was a threat, security staff quickly removed her from the studio.
Sergeant Neil Gunn of the Burbank Police Department in Los Angeles says Bradford was advised not to return to the studio or she would be arrested for trespassing.
An audience member told Access Hollywood that Bradford shouted at Farrell: 'I'll see you in court', to which he replied: 'You're insane!'
