John Lydon reportedly threatened to kill a fan at the Sex Pistols' first reunion gig in LA last night.

According to Reuters, the punk rocker was hit by a drink thrown by someone in the crowd, prompting him to accuse the individual of being a "coward".

During the set, which included the band's hits 'God Save The Queen' and 'Anarchy In The UK', Lydon apparently forgot the lyrics to the track 'Holidays In The Sun'.

When a female ran onstage during the show, Lydon commented: "Steve Jones always gets the fat ones."

The Sex Pistols play their first UK show in four years at the Brixton Academy on November 8.
