It's been 10 years since Adele dropped "21," and she's now reflecting back on the life-changing album.

"21" was released on Jan. 24, 2011, as a followup to her 2008 album "19." The album was a smash success, winning Adele Grammys for Album of the Year and Best Pop Vocal Album, as well as Guinness World Records in 2012 for digital sales in the U.K. and US, as well as consecutive and cumulative weeks in the No. 1 spot on U.K. charts by a solo female artist. Among the timeless singles from the album, which went many, many times platinum, were "Rolling in the Deep" and "Someone like You."
To celebrate the momentous occasion, Adele shared a photo of the album cover on Instagram. "Well I never! Happy 10 years old friend! It's crazy how little I remember of what it was like and how I felt a decade ago," she wrote in the caption. "But Thank You from the bottom of my heart for letting us into your lives and letting me be a soundtrack to some of it x."
Adele, who hasn't dropped new music since 2015's "25" — the followup to "21" — has left fans clamoring for more. Rumors are flying she could release new music sooner rather than later — perhaps as soon as February.
The singer's pal Alan Carr spoke to Grazia earlier this month about her new music. "I've actually heard some tracks on it. Oh my God, it's amazing – so amazing," he gushed. "I said to her, I said that voice is like an old friend, because there are some people in the charts who sound a bit like Adele and then when you hear Adele's voice, you go, 'Oh no, there's only one.'"
