Former X Factor act Cher Lloyd has sold one million copies of her debut US single Want U Back.
The track was released as a download two months ago. It entered the US iTunes Top 10 last month and has not left since.
The milestone follows Cher's radio tour of the US, which has seen the singer travel across the country.
She said of the achievement: "It's so amazing Want U Back has sold one million copies in America. My Brats rock, thank you!"
LA Reid, Chairman and CEO of Epic Records, said: “I’m very excited about the progress of Cher’s success. This is only the beginning!”
Cher is currently putting the finishing touches to her US debut album Sticks & Stones, which now has a new confirmed release date of October 2.
The American version of Sticks & Stones, released via Syco/Epic Records, will vary slightly from the 2011 UK version, including never-before-heard songs, as well as guests including Snoop Dogg who features on the album version of Want U Back.
Cher will make her second major US TV appearance on the Today Show on August 30. Her first was on America’s Got Talent last month, leading Perez Hilton to hail her 'insane talent, gorgeous voice’.
The New York Times dubbed her 'The Future', US MTV named her 'One To Watch', whilst Billboard Magazine called her 'Next To Ring Up The Chart' with 'one of the summer's most inescapable songs'.
