Adele has held on to the charts with Someone Like You staying as number one single for a second week and 21 the best-selling album for a fifth week.

Someone Like You went to the top of the singles chart last week in the wake of her show-stopping acoustic performance at the Brit Awards.

Official Charts Company managing director Martin Talbot said: "Adele is proving to truly be the star of 2011."

Someone Like You has sold more than 100,000 for two successive weeks.

Adele's debut album 19 moved up two places from four to two and another of her singles Rolling In The Deep remained at number four.

While her cover of Bob Dylan's Make You Feel My Love dropped one place from 24 to 25.

Last week, the singer-songwriter became the first living artist since The Beatles to achieve two top five hits in the Official Singles Chart and the Official Albums Chart simultaneously.

In January 1964, The Beatles' singles I Want To Hold Your Hand and She Loves You were at numbers two and five while albums With The Beatles and Please Please Me were at one and two.

Elsewhere in this week's singles chart, US actress Gwyneth Paltrow scored two top 40 single entries following her appearance on TV show Glee.

Her medley of Rihanna's Umbrella and Singing In The Rain entered at number 22 and a cover of Cee-Lo Green's chart-topper Forget You reached 31.

Jessie J - the ´óÏó´«Ã½'s Sound of 2011 and winner of the Critics Choice award at the Brits - remained at number two with her hit Price Tag featuring B.O.B.

Rihanna climbed three places to number three with her single S&M.
