Three months after having throat surgery
for a hemorrhaged vocal chord, Adele made a triumphant return at Sunday's Grammy Awards
, winning six trophies,
including album of the year, and performing publicly
for the first time since her health scare.
For the British singer, 23, it was clearly a night of relief as well as joy. "Mum, I love you. I'm so sorry you're not here," she said through sobs in accepting the album of the year award.
Her album, 21
, was "inspired by something that is really normal and everyone's been through it, which is a rubbish relationship," she added.
"And it's gone on to do things that ... I can't tell you how I feel about it. It's been the most life-changing year."
She also dazzled at the show with her performance
of "Rolling in the Deep," which had everyone rapt – partly to see how her voice would sound after the surgery.
So, what did you think? Did Adele sound different after her surgery? Tell us below.
