And the award for hottest couple at our Now Summer Party goes to...

If our #NowSummerParty wasn’t already hot enough, things started sizzling once Only The Young’s Betsy-Blue English and Stereo Kicks star Casey Johnson arrived.

The X Factor lovers who met on last years show looked every inch the pop perfect pairing as they spent the night side-by-side partying at our exclusive bash to launch Smart Girls Fake It summer skin care campaign with Superdrug .

After taking to the stage and performing her new single I Do with band mates Mikey Bromley, Charlie George and Parisa Tarjomani – the blonde beauty couldn’t help but gush about her boybander boyfriend.

‘We’ve just got back from our first holiday!’ the 19-year-old told us. ‘It was perfect, he said he’d marry me one day.’

And it wasn’t just the sassy songstress spilling all the deets of their holiday romance, the Stereo Kicker himself revealed some saucy bedroom secrets.

‘She covered the bed in petals and put a towel in the shape of a love heart in the middle,’ Casey told us. Which, um, Betsy quickly denied.

‘He’s lying! The hotel maid did that,’ she laughed in reply.

Well maid or not, we’re very much loving this relationship.

Not only did the pair find love on the X Factor, but both their bands have also bagged themselves record deals. Stereo Kicks have headed down the Sony route with single Love Me So out June 21st, while Only The Young’s I Do is set for a July release through Warner Music.
