NOTORIOUS Irish skirt-chaser Colin Farrell stripped down to his birthday suit to dance for mega-babe Sala Hayek - to settle her nerves about appearing nude in a flick.

Hayek was worred about losing her clothes in the 2006 film Ask The Dust.

The media buzz at the time was that the two were lovers and Farrell had performed a naked ballet dance.

But now he's come clean, telling Britain's Daily Star newspaper: "The naked part is true, but it wasn't ballet. It was a different dance.

"And I wasn't dating her - we were working together. We were doing a scene where she had to be naked, so I thought, 'I want to be naked'."
