has dropped out of the US top 10 album chart for the first time since it was released 18 months ago.
The UK singer's second album fell from number 8 last week to number 12 in this week's countdown after selling another 24,000 copies.
"21" was first released in the US in March 2011 and spent 78 consecutive weeks in the top 10 before falling this week.
The album is now tied with Michael Jackson's "Thriller"
and Def Leppard's "Hysteria"
for the third-longest run in the top 10 since 1963.
The two albums with the longest runs in the US top 10 are Bruce Springsteen's "Born In The U.S.A."
(84 weeks) and "The Sound Of Music"
soundtrack (109 weeks).
Earlier this month digital album sales passed the 100 million mark, with Adele and Ed Sheeran
two of the major UK stars helping to reach this milestone.
"21" has now sold around 10 million albums worldwide, smashing a slew of sales records along the way.
However, after the her Olympics performance produced a sales boost, Emeli Sande's
album "Our Version Of Events"
could be on course to overtake Adele's "21" as the biggest selling album of 2012.
