The clip sees the X Factor duo dressed in a red tailcoat jacket and black briefs, while they dance to a track titled 'Pop Rocket', which is taken from their upcoming album Victory.
Before unveiling the video, the pair wrote: "WHO IS EXCITED ABOUT OUR 300,000 VIDEO! WE ARE KINDA SCARED ABOUT UPLOADING IT! HOPING IT DOESNT GET BANNED.....ITS THAT AWESOME! (sic)"
The video was uploaded to YouTube, but taken down immediately on the grounds that the brothers do not have the copyright to distribute their new track online ahead of its release.
Jedward then released the celebration clip via Twitvid.
Jedward recently teased that they may be announced as a support act for some of Britney Spears's UK and Ireland dates, when the singer travels to Europe later this year.
The pair's new album Victory is out on August 5 in Ireland and August 15 in the UK.
