The 'Black Magic' hitmakers may have been busy preparing for their gig in Dublin as part of their 'Get Weird' arena tour last night but they still managed to make time to celebrate their support act's special day with a song and a tasty cake.

The former Wanted singer was relaxing in his dressing room ahead of his performance when the four girls - Perrie Edwards, Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall - bounded through his door singing 'Happy Birthday' in a Cockney London accent while carrying a desert adorned with candles and a special card.

Nathan looked on in surprise with his hands on his hips, before leaning in to blow out the candles.

Taking to his Twitter account afterwards, the handsome star uploaded a short video clip of the backstage shenanigans alongside the caption: "Bloody love these girls ... Thanks so much for the cake and birthday love @LittleMix (sic)"

And the girls weren't the only people hoping to celebrate the occasion as Jesy Nelson's fiancé, Rixton frontman Jake Roche, stopped by Nathan's dressing room before the gig to bring him some beers.

Jake tweeted: "@NathanSykes just came to your dressing room with beers. You wasn't there. So I sat in there and sung 'happy birthday' whilst drinking them. (sic)"

To which Nathan replied almost immediately: "Hahaha mate I'm so sorry! Shot off to dinner with the family tonight! Hope you saved me one for when I next see you! (sic)"
