Despite getting a bit of a rough reception from crowds here in the UK recently, it seems that the US market can't get enough of the pintsize popstar.
The track was released as a download two months ago and has today passed the million sales mark. It entered the Top 10 on US iTunes last month and has not left since.
These amazing sales follow Cher's radio tour of the USA, which has seen the singer travel across the country, winning new fans wherever she has gone.
Cher said in a statement: "It's so amazing 'Want U Back' has sold one million copies in America. My Brats rock, thank you!"
Chairman and CEO of Epic Records, and X Factor USA judge, LA Reid added: “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 highly anticipated US debut album Sticks & Stones, which now has a new confirmed release date of October 2nd. The American version of Sticks & Stones, released via Syco/Epic Records, will vary slightly from the 2011 UK version. The US album includes never-before-heard songs, as well as a few surprise guests including Snoop Dogg who features on the album version of 'Want U Back'.
Cher is winning over US fans by the masses, as proven by her afternoon of fan-packed mayhem during a recent visit to West Hollywood’s Millions of Milkshakes. Police had to intervene as several thousand of Cher’s beloved “Brats” mobbed the streets for a glimpse of her.
