Twenty-year-old singer/songwriter Ed Sheeran said he was "ecstatic, really happy and pleased" to be the most nominated musician of the year ahead of the 2012 Brit Awards.
Contenders were revealed at a red carpet event in London last night, with Sheeran recognised in four categories - best British breakthrough act, male solo artist, British single and British album of the year.
Jessie J, also up for best breakthrough act and single, as well as best British female solo artist, said: "I would never have imagined this last year. I remember sitting at the table and thinking, 'Next year I want to be voted best female'.
"Even if I don't win, it's just being nominated and the feeling of that."
The Price Tag singer competes for best single and female solo artist with fellow singer/songwriter Adele, who also takes on Sheeran for album of the year.
Jessie J and Sheeran are joined in the British breakthrough act category by fellow newcomers Anna Calvi, Emeli Sandé and the Vaccines, while Sandé, Maverick Sabre and Michael Kiwanuka make up the critics' choice shortlist.
