This might be our closest Battle of the Brits matchup yet! In the final round of Pop Solo artists (also our Quarterfinals), Jessie J is going head-to-head with Ellie Goulding.

Round 2 was a tough fight for Jessie J. She barely beat out Adele, taking just over 50% of the votes. That's a huge score for the singer! After all, Adele is still riding high after winning an Oscar earlier this year. 2013 promises to be major for Jessie J as well. The 'The Voice UK' mentor is set to release an album later this year.

Last round, Ellie Goulding ousted Cher Lloyd, claiming 53% of the vote, but will she be able to beat Jessie J? Goulding has made a name for herself, collaborating with musicians like Tinie Tempah and Calvin Harris. Plus, she performed at a casual event you might have heard of -- Prince William and Kate Middleton's wedding reception.

It will certainly be a close match! Remember, you can vote once an hour until the polls close at 2PM ET on Aug. 14. Go, go, go!
