How many albums did usher sell on his last album?

As of my last update in October 2023, Usher's most recent album, "Confessions," released in 2004, has sold over 10 million copies in the U.S. alone, making it one of his best-selling albums. However, if you're referring to a more recent release, please specify the album, as my data may not include the latest sales figures for subsequent albums.
