The 'Price Tag' singer picked up the Critics Choice trophy at last night's (15.02.11) ceremony, held at London's The O2 venue, and said she wants to spearhead a new breed of British superstars.
She told the Metro newspaper: "I am proud to say that I am British and I am proud to say that I am ready to take on the likes of Pink and Beyonce and Katy Perry and really make a name for British icons.
"I know it is a big thing to say but I am ready for it. Whether it happens or not I believe I can push boundaries. As long as I am happy and I am doing me then I can't make any mistakes really."
However, the 22-year-old brunette says she'd also be more than willing to work with those she sees as competition, adding she'd "love" to join Beyonce on stage at Britain's Glastonbury Festival "if she'd let her".
Jessie is also working hard at her goal, admitting her schedule is so full she doesn't have any days off in the near future.
She told Absolute Radio: "I'm doing every festival this year - Glastonbury, Reading, I'm booked for everything. My next day off is in 2013!"
"I've worked really hard for the last six years and it's great for the critics to see that and to see that I've been working hard and to be number one for two weeks and to have the respect of my fans.
"Now I'm just making sure that I don't presume and I always work hard and I'm here working my butt off to take British music global."
