Rak-Su are happy having at least one heartthrob in the band.

The 'X Factor' winners have addressed band member Myles Stephenson's reported fling with 'Love Island' beauty Malin Andersson, and reassured their fans that they are ensuring the hunky star's ''ego'' stays ''in-check''.

Ashley Fongho - who completes the group along with Mustafa Rahimtulla and Jamaal Shurland - told The Sun newspaper: ''There's only one heartthrob, but his ego stays in check and he's not arrogant about it.

''We love Myles.''

Myles, 25, hasn't been short of female attention since the group swiped the crown last weekend but, although they were told not to get into any relationships while competing on the series, he reportedly hooked up with the star from last year's series of the dating show.

A source previously revealed: ''Myles clearly took a fancy to Malin after she made contact on Twitter and Instagram. They met up in secret and enjoyed a few nights together at her home in Milton Keynes before going their separate ways.

''It was a cheeky move by Myles given that X Factor's bosses ask contestants to concentrate on the show while they were still involved.''

However, their relationship was short lived as Myles realised he still had feelings for his ex-girlfriend Rebecca Bignell - who he split from once his band made the live rounds of the show - and couldn't given Malin what she wanted emotionally.

And it doesn't look like Myles will be rekindling his romance with Rebecca as the foursome decided to focus on their music for the time being and side line any relationships.

Ashley said recently: ''We've had a lot of female interest since we went on 'X Factor'. We've had messages on social media but we haven't been responding. While you're on the show it just isn't possible, and now we've got to focus on our music.''

And the quartet revealed they already have a back catalogue of tracks ready to release, and can't wait to get into the recording studio - leaving no time for partying.

Jamaal explained: ''We want to take our music around the world.

''We're not going to wait like some other winners have. We've got an advantage because we already have our own material ready to go.''
