Adele looked stunning at the BRIT Awards earlier this week taking home the Best Song, Album of the Year, and Artist of the Year awards.
Fans noticed the star's impressive transformation when she appeared on Saturday Night Live in October 2020 after losing seven stone.
She said: "I know I look really, really different since you last saw me. But actually, because of all the Covid restrictions… I had to travel light and I could only bring half of me, and this is the half I chose."
Adele revealed she managed to lose weight through exercise: "Working out, I would just feel better."
However, she explained her goal wasn't to lose weight but to improve her mental health.

"It was because of my anxiety," Adele told British Vogue.
"It was never about losing weight, it was always about becoming strong and giving myself as much time every day without my phone. I got quite addicted to it."
But what routine did she follow?
The singer explained: "So I do my weights in the morning, then I normally hike or I box in the afternoon, and then I go and do my cardio at night.
