Rak-Su and Grace Davies head to Birmingham for The X Factor Live

The X Factor Live will feature winners Rak-Su alongside Grace Davies, Kevin Davy White, Matt Linnen, Lloyd Macey, The Culkelvins and Sean & Conor Price.

Rak-Su swept to victory after forming in Watford and being mentored by Simon Cowell. The group comprises Ashley Fongo, Jamaal Shurland, Mustafa Rahimtulla and Myles Stephenson.

Their winning single, Dimelo, featured Naughty Boy and Wyclef Jean and entered the singles chart at number two, behind Ed Sheeran’s Perfect.

They were in the top two with Grace and finished as the winners with more than half of the vote. They are the second group to win the show after Little Mix and the first male group to win the show. Their lives have been transformed since winning TV’s most popular music show.

Jamaal was working as a neuro-physio assistant in the NHS. He says: “I’d got accepted to do a Masters in physiotherapy. But it was too expensive to do so I had to defer the course for a year then The X Factor came up. It’s something I really want to do in the future, but it might be hard being famous and a physio, although the phone might be ringing off the hook.”

Mustafa, meanwhile, worked in the hotel business.

Grace Davis came close to victory having become an online sensation before wowing both the X Factor judges and viewers at home with her beautiful and infectious songs.

From Roots in her first audition to Hesitate and Wolves, her tracks stormed up the iTunes chart and secured her as one of the favourites.

The Blackburn singer, 20, says the attention that The X Factor stars receive is alarming.

“It’s madness. It’s something that you’ve really got to get used to. It’s made me a stronger person and I feel like a different person since my first audition. I watched it back the other day, and I was like, ‘Wow, how things have changed.’ And no one can prepare you for this experience ever, because it’s like, ‘OK, now you’re in the public eye. Deal with that’. But it’s genuinely the most incredible thing, because people see your music and they hear your voice.

“I think I’m just a lot stronger. I was very vulnerable when I walked into that audition because I’d been doing music for a while, writing songs every day and I was living somewhere completely far away from home not earning any money. I was just sad that it wasn’t going anywhere.

“So when I walked into that audition, I was probably a bit giggly and a bit giddy and a bit like ‘please like me!’ So I think now I feel like myself again, the artist that I’ve always wanted to be.”
