Adele is enjoying her fourth consecutive week at number 1 tonight (February 20) with her sophomore record '21'. 

The 'Rolling In The Deep' star's debut album, '19', has also climbed 2 places in this week's UK album chart to 4 and her presence in the top 40 was undoubtedly helped by her stunning performance of 'Someone Like You' at the 2011 BRIT Awards. 

Mumford & Sons have shot up a whopping 13 places with 'Sigh No More' to number 2, Rihanna's 'Loud' is a non-mover at 3 and Bruno Mars' 'Doo Wops & Hooligans' completes the top 5.
