The singer Estelle won two awards at last night's Mobos, on a night dominated by British artists.
The 28-year-old was tipped for success after being nominated for five awards, and won Best UK Female and Best Song for her single "American Boy".
In her acceptance speech, she said she gives all the prizes she wins to her mother, who "puts them on the shelf". She completed the celebrations by singing a duet alongside her manager, the soul singer John Legend.
Another British singer, Leona Lewis, also picked up two awards, winning Best Album for Spirit and Best Video for her song "Bleeding Love". However, she was booed after the audience realised she could not be at the ceremony to pick up either of her awards. Several other artists were also heckled when it was revealed they were not there in person.
Lewis, 23, achieved prominence after winning the third series of the reality television show The X Factor in 2006. She proved as popular in the United States as she did in the UK, going on to become the first British woman to reach number one in the US singles charts for more than 20 years.
The annual event, which marks the year's best Music Of Black Origin, was held at Wembley Arena and was hosted by the former Spice Girl band member Mel B and Rev Run, one of the founding members of the American hip-hop group Run DMC.
The rapper Dizzee Rascal was voted Best UK Male for the second year running, while MC Chipmunk, 18, was chosen as Best UK Newcomer. The British saxophonist YolanDa Brown won the Best Jazz category, and the Best DJ prize was won by BBC Radio 1 DJ Trevor Nelson.
US stars were also recognised, with Chris Brown – who has been called the "new Michael Jackson" – winning two awards. Mary Wilson, a former member of the Supremes, collected a Lifetime Achievement Award on behalf of the Motown label, which celebrates its 50th anniversary in January.
Kanya King, founder and CEO of the event, said: "The Mobo awards have continued to grow in strength for the past 13 years, and I'm particularly delighted that British talent through artists such as Estelle and Leona receive the recognition they justly deserve. I hope we can inspire a new generation of talent to follow their lead and fulfil their dreams to one day appear on our show."
