The record sold 352,000 copies of the album this week and is the biggest-selling album in the US this year so far.

'21' is now at number one on both sides of the Atlantic.

In the UK, Adele recently became the only living artist to tie The Beatles 1964 record of having two entries in the top 5 on both the UK singles and album charts.

Meanwhile, elsewhere on the Billboard countdown, Justin Bieber was at number two with 'Never Say Never: the Remixes'.

Mumford & Sons were at three with 'Sigh No More', while the top-5 was completed by the 'Now 37' compilation album and Bieber's 'My World' at four and five respectively.
