Lady Gaga has thanked fans around the world after they helped her raise more than $500,000 for earthquake-ravaged Haiti – in a single day!

The singer dedicated 24 January to raising funds for the Caribbean country, pledging to donate proceeds from a New York concert and merchandise sold on her website.

And at her concert on Tuesday at Purdue University, where she concluded the U.S. leg of her Monster Ball Tour, Lady Gaga announced the results of her fans’ donations. She told the audience:

“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! So let’s sing along for Haiti right now!”
