The star's second album reaches a new sales landmark around the world following work with James Bond franchise.
Adele's second album '21' has now sold over 25 million copies worldwide.
The announcement, revealed by Music Week, comes just days after the album went diamond in America – an certificate awarded after an album sells more than 10 million copies.
On Twitter, Adele thanked her fans and jokingly told them to "shine bright like a diamond" - a reference to Rihanna's recent single 'Diamonds'.
Despite keeping a relatively low profile after becoming a mother for the first time, the 2011 album has continued to prove popular with music fans around the world.
In the UK, '21' has sold 4.5 million copies, while fans of the star have also snapped up copies of her 'Live At The Royal Albert Hall DVD'.
Earlier this year, '21' also equaled records set by Prince and the soundtrack to Saturday Night Live after it spent 24 weeks at the top of the Billboard chart.
Adele's recent single for the James Bond film Skyfall has also sold two million copies.
