Adele released her second album, 21, in early 2011. The album was well received critically and surpassed the success of her debut. 21 helped Adele earn six Grammy Awards in 2012 including Album of the Year, equalling the record for most Grammy Awards won by a female artist in one night. The album has also helped her receive numerous other awards, including two Brit Awards and three American Music Awards. The album has been certified 15 times platinum in the UK; in the US the album has held the top position longer than any other album since 1985.
The success of 21 earned Adele numerous mentions in the Guinness Book Of World Records. She is the first artist to sell more than 3 million copies of an album in a year in the UK. With her two albums and the first two singles from 21, "Rolling in the Deep" and "Someone Like You", Adele became the first living artist to achieve the feat of two top five hits in both the UK Official Singles Chart and the Official Albums Chart simultaneously since the Beatles in 1964. With her third release from the album, "Set Fire to the Rain", becoming her third number one single in the US, Adele became the first artist in history to lead the Billboard 200 concurrently with three Billboard Hot 100 number ones. Adele is also the first female artist to have three singles in the top 10 of the Billboard Hot 100 at the same time, and the first female artist to have two albums in the top five of the Billboard 200 and two singles in the top five of the Billboard Hot 100 simultaneously. 21 is the longest running number one album by a female solo artist on the UK Albums Chart and is the longest running number one album by a female in Billboard history. In 2011, Billboard named Adele artist of the year.
