Adele and Rihanna latest to sell one million singles
Adele's Rolling in the Deep and Rihanna's Diamonds are the latest singles to sell more than one million copies in the UK.
They are the 144th and 145th tracks to reach the milestone, according to data from the Official Charts Company.
Rolling in the Deep is Adele's second million-seller following Someone Like You.
It peaked at number two in the chart and was the lead single from her bestselling album, 21.
The album is the fourth biggest-selling of all time with more than 4.6 million copies sold.
Diamonds, which was a number one single in October 2012, is Rihanna's fourth song to sell more than one million copies in the UK.
She is now second only to The Beatles for the most million-selling singles, according to the Official Charts Company.
Her previous million-sellers are We Found Love featuring Calvin Harris, Love The Way You Lie with Eminem (2010) and Only Girl In The World (2010).
"In securing their second and fourth million sellers respectively, Adele and Rihanna join an elevated group of artists," said the Official Charts Company's chief executive, Martin Talbot.
"It is a tribute to their massive popularity that they have achieved such accolades.
"Few artists from any era have achieved ONE million seller in the UK, let alone multiple ones.
"It is also particularly apt, that they have done so in the days leading up to International Women's Day."
The news comes a week after Pharrell Williams scored his third million-selling single in less than 12 months with Happy.
