Duffy now has three Brit awards to her name after winning British female, British breakthrough and British album at Wednesday night's ceremony in London's Earls Court.
Coldplay, after losing out on four awards, had a good crack at mastering the art of not looking too disappointed.
There was plenty going on backstage too though and while Duffy may have been the big winner, she was also the only one to shock reporters with her potty mouth during the press conference.
"I'm not going to lie to you all. It's really not easy. It's hard. It's really hard. I hope we're not live!" Just the one TV crew, actually Duffy.
"I really hate swearing," she continued. "But I wanted to stress that. You sacrifice something, you do music - you don't know what you're doing it for.
"And then suddenly you get a night like tonight, which says, you know what? You have been recognised. So I'm very happy."
Gavin & Stacey stars James Corden and Mathew Horne must be feeling pretty happy with themselves right now too after pulling off hosting the event with Kylie.
They appeared either side of Kylie, wearing red dresses and knee-high, black plastic boots and dancing to I Just Can't Get You Out Of My Head, looking like they were loving it.
Looking much more comfortable, in fact, than on the red carpet a few moments before, as they unburdened their nerves onto Newsbeat.

"We don't want to let anybody down. We really want to do the best show that we can. We've got a great line-up and the last thing we want to do is be the loose cog in that wheel."
No worries there then. Take That fans, however, were left a little disappointed, but not by the boys who looked great in tight, black outfits, Clark Kent glasses and slicked-back hair.
Someone had gone and started a rumour Robbie was going to join them for their performance.
Sadly not true despite them arriving on stage in an alien spaceship.
It truly felt like Robbie might appear out of it, right up until the very last moment it disappeared back into the ceiling.
Honorary Brits Kings of Leon might were handed two awards, international group and international album for Only By The Night.
They had the whole room up on their feet dancing, including all of Girls Aloud and Duffy and were very honoured to win.
They said: "Everything about this band is owed to the British fans.
American record labels would have definitely given up on us by now, but thanks to you guys we get to do whatever we want in America now, so it's great."
Caleb and the rest of the Followill clan also had some rather individual plans for celebrating.
"For now we're just going to enjoy the moment and get our trophies drunk tonight." Which sounds like something British group winners Elbow might enjoy.
Guy Garvey and his band were so excited to beat Take That and Coldplay that Newsbeat spotted them marching around backstage, hugging a giant model of a Brit award they'd nicked off the set.
