Adele is finally opening up about her new album, "25" (XL/Columbia).

The Grammy-winning singer posted a note on Twitter Wednesday morning discussing the album, which will be released Nov. 20, for the first time.

"My last record was a break-up record and if I had to label this one, I would call it a make-up record," she wrote. "I'm making up with myself. Making up for everything I ever did and never did. But I haven't got time to hold on to the crumbs of my past like I used to. What's done is done."

While most artists start laying the groundwork for a new album three to six months before its release, Adele seems to be going for a stealthier approach.

On Sunday, a mysterious 30-second song snippet thought to be from Adele's new album aired in an ad during "The X Factor" in the United Kingdom with no explanation or identification.

Of course, Adele can afford not to have a massive rollout for "25," considering that it follows 2011's "21," which was recently certified diamond for sales of more than 10 million and is the top-selling album of the decade. The breakup album featured the hits "Rolling in the Deep," "Rumor Has It" and "Someone Like You."

"I miss everything about my past, the good and the bad, but only because it won't come back," Adele wrote. "When I was in it, I wanted out! So typical."

Tobias Jesso Jr., one of the year's breakout artists, has reportedly contributed a song, while producers Danger Mouse and Ryan Tedder have been working with her on new material. 

" '25' is about getting to know who I've become without realizing," Adele wrote. "And I'm sorry it took so long, but you know, life happened."
