The Dog Days Are Over hitmakers took the project to number one in their native Britain on Sunday (07Jun15) and now they have been given double the reason to celebrate by claiming the Billboard 200 title, too.

The latest feat marks Florence + The MAChine's first U.S. chart-topper - 2011's Ceremonials reached number six and their 2009 debut peaked at 14.

They replace A$AP Rocky at the top of the countdown - his At.Long.Last.A$AP slips to three, behind Taylor Swift's 1989, which stays put at two.

Jason Derulo is a new entry at four with the appropriately-titled Everything Is 4, while Ed Sheeran's X rounds out the new top five.

Meanwhile, in the Billboard Hot 100, Wiz Khalifa racks up his eighth week in first place with See You Again, fighting off competition from Swift's Bad Blood and Fetty Wap's Trap Queen, which remain at two and three, respectively.
