Lady Gaga raised over $500,000 for Haiti on Sunday, matching the impressive figure amassed by Radiohead.

All proceeds from Gaga's show at the Radio City Music Hall show, plus all the merchandise profits on the singer's official website went to the relief effort in the earthquake ravaged Caribbean nation.

The singer said: "On Gaga For Haiti day, in just 24 hours, with very minimal marketing and planning, all the little monsters all over the world made over half a million dollars for Haiti relief.

"I know Bravado fell off their chair, that's who sells all my merchandise - they couldn't believe it!”

On the same night, Radiohead's one-off show at The Music Box Theater in Hollywood amassed $572,000 for Haiti after fans bought tickets via an online auction.

Hollywood stars Charlize Theron, Daniel Craig, Rosanna Arquette and Justin Timberlake were just some of those in attendance.
