JUSTIN BIEBER BACK ON TOP

Justin Bieber has toppled his mentor Usher from the top of the album charts.

The R+B star knocked the youngster's My World 2.0 album on the Billboard 200 countdown last week (07Apr10), but the teen has bounced back.

The album has swapped places on the chart with Usher's Raymond v Raymond.

Slash scores the week's highest debut at three with his self-titled album, which features guests spots from the likes of Lemmy, Ozzy Osbourne, Kid Rock and Fergie.

Meanwhile, Madonna scores her 19th top 10 album - her Sticky + Sweet Tour debuts at 10.
