Sean is now predominantly based in New York
Jay Sean swept the boards at the 2010 Asian Music Awards by winning every prize for which he was nominated.
The singer took best male, best album for All or Nothing, best video for Down and best urban act at the ceremony, held in London's Royal Festival Hall.
Amar claimed the best female act, while JK was voted the best newcomer.
Other notable winners included Imran Khan for best Desi (south Asian) act, while Sukshinder Shinda earned the award for best producer.
"It's a great feeling to get four out of four," 26-year-old Sean told BBC Asian Network, and revealed he had also bagged a guest superstar for his next single.
"I've recently done a collaboration with Mary J Blige," he said. "It was incredible and we are shooting the video in London on Friday."
The Hounslow-born R&B singer generated a huge roar of approval from the crowd - along with fellow nominees Imran Khan, Jaz Dhami and Mumzy Stranger - whenever their names were mentioned.
And, even though Sean came out on top, Dhami and Khan did produce two of the highlights of the awards.
The white-suited Dhami opened the show as a grand piano and violinist provided the backdrop to his singing, while Khan put on a performance which saw him drape a snake around him as he sang a medley of his songs.
"You have to do something different to stand out in the industry and I did it," said Khan, who had a huge hit with his single Amplifier. "I loved it."
British boxer and WBA light-welterweight champion Amir Khan added: "I think that's the first time I've seen a real snake - I hate snakes as well.
"There were some crazy acts going on. I loved it. I've heard a lot about the event and, although it's the first time I've come to them, I think I'll be here again."
The Sugababes also put in a performance at the ceremony, as they revealed that they will be going to India to perform at the lucrative Indian Premier League cricket tournament.
