It's been a whole three years since Adele released her last record, "Skyfall", and two years since she made her last public appearance, at the 2013 Grammys.
In that time she's been pretty busy – she got engaged and had a baby boy, Angelo.
But on Sunday night, when the first 30 seconds of what appeared to be her new single were played during an ad break in The X Factor, people collectively lost their minds.
Well, now Adele has written a lovely blog post about her life, explaining the reason for her time out of the spotlight.
She said she feels as though she’s spent most of her life “wishing it away”.
I feel like I've spent my whole life so far wishing it away. Always wishing I was older, wishing I was somewhere else, wishing I could remember and wishing I could forget too. Wishing I hadn't ruined so many good things because I was scared or bored…Wishing I didn't know myself so well, because it means I always know what's going to happen in the end.
Adele said she no longer wants to live according to her past and that her 25th birthday was a massive turning point for her.
I haven't got time to hold on to the crumbs of my past like I used to. What's done is done. Turning 25 was a turning point for me, slap bang in the middle of my twenties. Teetering on the edge of being an old adolescent and a fully-fledged adult, I made the decision to go into becoming who I'm going to be forever without a removal van full of my old junk.
She also made reference to the past and being a teenager, living without consequence.
I miss … being a teenager, sitting around and chatting shit, not caring about the future because it didn't matter then like it does now. The ability to be flippant about everything and there be no consequences.
