Hollywood actress Gwyneth Paltrow showed off her vocal talents at a charity karaoke show in London - after a $90,000 bid prompted her to take to the stage.

Paltrow was taking part in the Karaoke With The Stars event on Thursday night at the city's famous Ronnie Scott's jazz bar - helping raise money Palestinian refugee children. And the Iron Man star's offer to sing attracted the highest amount of bids, with Paltrow eventually stepping up to the microphone for a rendition of Roberta Flack's classic Killing Me Softly.

Model-turned-actress Lily Cole also took to the stage, joining Bryan Ferry for a performance of his hit track Let's Stick Together.

The event raised over $440,000 for good causes.
