Adele's record-breaking 25 album has now sailed past five million sales in the U.S.

The Hello singer released her third studio album on 20 November (15), and in its third week on sale, the disc has sold another 510,000 copies, pushing her over the five million mark, according to Billboard.

She shattered 'N SYNC's single-week sales record by chalking up 3.38 million units in her first week, and then became the first artist to record two successive one million sales weeks seven days later.

Her new record bests one she set in 2011 when she sold five million copies of 21 in a calendar year.

25 is now one of only 11 albums released since 2005 to sell five million units.
