Adele's album sales spike lands her another record

Adele continues to make chart history - sales of her Grammy Award-winning album 21 has spiked by almost 500,000 in the last week.

It's the biggest gain ever for a female artist since chart compilers Nielsen SoundScan began tracking data in 1991.

The album scored a 21st week at the top of the Billboard 200 with sales topping 730,000 thanks in part to Adele's performance at the Grammy Awards, where she scooped six top trophies.

The ceremony marked her return to the live stage following throat surgery last year (11).
