Chart-topper Jessie J had tears in her eyes after she swept the board at the Mobo Awards, winning four out of five categories she was nominated for.
The Price Tag singer, who was born Jessica Cornish, won best UK act, best newcomer, best song for Do It Like A Dude and best album for Who You Are.
But the Essex-born music star missed out on the best video award, beaten by Tinchy Stryder and Dappy with the song Spaceship.
With tears rolling down her face she told reporters, after the show finished in Glasgow last night: "It's just overwhelming, I'm so honoured,"
The singer and songwriter also opened the show, wearing a sparkling baseball hat, with a fairly energetic performance of Do It Like A Dude.
After picking up her first award of the night for best album, she told the audience: "Wow. I did not expect to win that at all.
"I just want to say the biggest thank you to my fans because I watched this last year by myself in my living room and no one knew who I was and now I just won best album.
"That is epic. Thank you everyone."
The singer, who also thanked her parents on stage, told reporters the black Dr Martens boots she had on were all she could fit her swollen foot into following an injury earlier this year.
The night also featured a tribute to Amy Winehouse, led by her goddaughter Dionne Bromfield, who sang Love Is A Losing Game.
Winehouse was found dead at her flat in north London on July 23. She was 27.
The Back To Black singer had fought a lengthy public battle with drink and drug problems but toxicology results showed there were no illegal substances in her system.
Speaking ahead of performing the tribute, Dionne, the 15-year-old who was also nominated for the best UK R&B/soul act, said: "It's amazing. It's really emotional but I'm really pleased to be doing it.
"Amy loved the Mobos, it was one of her favourite awards."
Stars on the red carpet included JLS, Myleene Klass, lingerie entrepreneur Michelle Mone and Tinie Tempah, who won best Hip Hop/Grime act.
US singer Alexis Jordan sang her hit Happiness and Katy B and Ms Dynamite also performed the song Lights On during the show.
Neither Adele nor Rihanna, who won the best international star, were at the show at Glasgow's Scottish Exhibition and Conference Centre (SECC).
In a video message played after she was announced as winner of the best R&B/soul act, Adele said: "Thank you very much for this Mobo award. It means a lot to me. I'm so sorry that I can't be with you there tonight."
She said she was on her way to America for her tour and congratulated the other nominees and winners.
American R&B group Boyz II Men were also awarded a prize for an outstanding contribution to music.
Nathan Morris said: "Europe has been a very, very big part of Boyz II Men's history."
Thanking fans for their support, Shawn Stockman said: "Hopefully there will be another 20 years, we thank you so very much Glasgow, we love you, thank you."
It is just the second time the Mobo Awards have been staged in Scotland and the third year in a row the event has been staged outside London.
Kanya King, founder of Mobo, said: "Jessie's opening number, I think people will remember that for a long time to come.
"The excitement and atmosphere of our second year here in Glasgow has shown the love that the whole country has for Mobo. We felt so welcome the first time we came here, we didn't think it could be topped. This year has been a phenomenal success and we can't wait to return in 2013."
