The 'Wild Heart' hitmakers are set to support the chart-topping boy band on their 'Word of Mouth' farewell tour later this year, but the teen heartthrobs - consisting of Connor Ball, James McVey, Tristan Evans and Bradley Simpson - insist they won't allow girlfriends to get in the way of the band.
The declaration of unity comes after Wanted star Max George admitted the 'Glad You Came' group's personal lives affected the band and he didn't get along with Siva Kaneswaran's fiancée Nareesha McCaffrey.
Quizzed if they were worried about falling out, Tristan said: ''No, definitely not. Bros before women!''
Bradley added: ''I think we're all a pretty solid unit.''
The boy band, who will also support Taylor Swift on the UK leg of her 'Red' world tour next month, say they're ''lucky'' to be part of The Wanted's final gigs.
Bradley said: ''We're very lucky that we're going on their last ever tour, which is kind of weird.''
The Vamps will release their debut album in March and the record will be similar to their recent chart hit 'Wild Heart'.
Bradley revealed to BANG Showbiz: '''Wild Heart', that's definitely more the running theme ... the instrumentation on that runs through the album.''
The Vamps were at the launch of 'Call of Duty: Ghosts Onslaught', the first DLC Pack for 'Call of Duty: Ghosts' which launches first on Xbox Live on Tuesday 28th January. Find out more about the four new multiplayer maps and new episodic Extinction story line at www.callofduty.com.
