The awards, which are voted for entirely by the public, saw the ‘All Time Low’ singers narrowly take the title from One Direction gaining just 0.08% more than the ‘Little Things’ group.
Despite leading the poll throughout the voting process, The Wanted managed to sneak up on One Direction in the final stages.
However, we doubt One Direction are feeling particularly down about missing out on the title considering they are still in the running to win a BRIT for Best Group later this month.
The Wanted and One Direction have made no secret about their rivalry- previously engaging in some very public spats.
Jay McGuinness of The Wanted said of the rivalry: "I mean, there's obviously mouth there. We used to try and have a bit of banter with them, and they kind of ignored it for a while.
"But I think now, with the fanbase growing, and it getting brought up what we said ages ago, I think they've let it rile them a little bit."
Meanwhile One Direction member Louis Tomlinson said: "If you want to create that rivalry, then let's do it.
"We're not bothered about the friction or the rivalry. But I'm not going to shy away from it because that isn't the person I am."
Other winners from the awards, which saw over one million people vote, included Justin Bieber who won ‘Best Solo Artist’ over favoutite Rihanna by gaining an impressive 56% of the votes.
