Country trio Lady Antebellum are back at the top of the album charts with the biggest opening week sales for a group this year.

The band's "Own the Night" has debuted at number one on the Billboard 200 with 347,000 sales.

Only three country groups have scored chart-toppers - Lady Antebellum, the Dixie Chicks and Rascal Flatts.

Adele's "21" has stayed put at two on the new chart, while Lil Wayne's "Tha Carter IV" falls from the top spot to number three.

Country singer Brantley Gilbert's "Halfway to Heaven" and Staind's eponymous new album round out the new top five.
