The Vamps have been named as the winners of MTV Brand New 2014.
The indie pop band feel "very lucky" after two months of campaigning for votes and beating off stiff competition from BRITs Critics' Choice Award winner Sam Smith to the coveted title.
Drummer Tristan Evans told MTV: "We're very lucky and we feel very humbled and honoured to win such an awesome competition we've been growing up with."
Among other nominees this year for MTV Brand New were - Ella Eyre, Elyar Fox, BANKS, Royal Blood, Joel Compass, Kwabs, George Ezra and unsigned winner Marie Naffah.
The Vamps - which also features Bradley Simpson, Connor Ball and James McVey - follow in the footsteps of Ebony Day, Conor Maynard and Justin Bieber who are previous MTV Brand New champions.
Bradley added: "A big thank you to all our fans who voted for us, you're all amazing. It's a bit weird winning it when we've all grown up and seen the artists who have won it so thank you very much."
The 'Wild Heart' hitmakers' increasingly large fan base - nicknamed the vampettes - helped their debut single 'Can We Dance' reach number two in the UK Official Singles Chart last year, however they have previously brushed off a rivalry with One Direction.
They said: "We don't look at any other bands as competition. There is a massive music industry [and] there is space for loads of different bands, so it's not a competition."

The Cure are set to release a new album. The 'Friday I'm In Love' band, who will play two sold out Teenage Cancer Trust shows at London's Royal Albert Hall next month, plan to drop their 14th studio album, the follow-up to their 2008's '4:13 Dream' th...

Blur drummer Dave Rowntree admits people still apologise for mentioning Oasis in front of him.
During his pre-recorded radio show on XFM, which will air on Thursday (06.02.14), the musician plays Oasis hit 'Stop Crying Your Heart' and introduces the track by revealing people still think he's "bitter" about the two bands' rivalry during the 1990s.
He tells listeners: "When people around me inadvertently mention something to do with Oasis, or to do with something to do with Oasis, they generally turn to me and apologise.
"So if they say: 'I remember when I bought 'Roll With It'', they go, 'Sorry Dave!' Or they say, 'I think the new Beady Eye single's quite good ... Sorry Dave!'. So clearly people think that I'm still bitter about the battle of Britpop."
Blur were locked in a constant chart battle with Oasis in the mid-1990s, which culminated in them releasing singles in the same week in 1995, with Blur's 'Country House' topping the chart above their rivals' track 'Roll With It'.
After a huge backstage argument between frontman Liam Gallagher and his guitarist brother Noel, Oasis split in 2009 and the siblings have barely spoken since, instead deciding to focus on separate careers with Beady Eye and Noel Gallagher's High Flying Birds.
Meanwhile, Blur split in 2003 but reunited in 2008 and frontman Damon Albarn confirmed last summer that he will reunite with his bandmates - Dave, bassist Alex James and guitarist Graham Coxon - to record a new album following the release of his own solo LP this year.
Last week, The Who frontman Roger Daltrey hinted that he would like to try and get Oasis to reunite for a Teenage Cancer Trust gig next year.
He said: "Noel and Liam are brothers so it will all be alright. Don't worry. Blood is thicker than music...
"Could I bring them together for a Teenage Cancer Trust show? Ask me next year."

Miley Cyrus wants people to focus more on her singing.
The 'We Can't Stop' hitmaker insists she doesn't want to be known for her shock value and hopes people will remember her for her voice and not her raunchy dance moves.
She explained to the US version of OK! Magazine: "I'm more focused on people being excited about me as a singer rather than someone who shocks people.
"I want people to be like, 'She did some things that were crazy, but at the end of the day it was all about her voice'."
Miley made headlines last August after her controversial performance at the MTV Video Music Awards - during which she stripped down to a latex bikini and grinded against 'Blurred Lines' singer Robin Thicke.
But Miley is adamant the intentions behind her antics are positive and claims she's a feminist.
She added: "I know people make it seem like all I do is come out and shock people. That isn't what it is. I think what girls see is that there's a feminist energy there."
Meanwhile, the 21-year-old singer revealed she takes time out to relax in order curb her nerves before a show.
She explained: "If I get nervous I need to lock it down. I need to sit out, get my mind right and rest my voice ... I want it to be something that's worth going to see."
