It's the Semifinals in PopCrush's Battle of the Brits, meaning there's four acts left battling it out for the ultimate crown! 

Each of the remaining acts (whether they be Irish, British, Scottish or Welsh) had to go through three rigorous battles to get to the semifinals, and had to rely on you, the voters, to make it this far! The remaining acts, who also won in their respective categories are: Jessie J (Pop Solo), One Direction (Groups and Bands), Marina + the Diamonds (Singer-Songwriter) and Calvin Harris (Electronic).

The first battle has Jessie J facing off One Direction. Does the 'Excuse My Rude' singer have enough attitude and swagger to triumph over Harry, Zayn, Niall, Liam and Louis, aka the boys who don't dance?

And in our other battle, singer-songwriter Marina + the Diamonds is facing off Scottish DJ Calvin Harris. Marina's known for her excellent songwriting skills and powerhouse vocals, but she'll have to compete with Calvin, who has top-charting hits with Florence Welch, Rihanna and Ellie Goulding!

So who do you want to go on to the championship round? The polls for the semifinals will close on Aug. 28 at 2PM ET, and you can vote once per hour until then. Good luck, and start voting for the ultimate U.K. artist below!
