But she revealed she hasn’t completed her weight loss goal yet, she said: “I’ve still got a bit to go, I want to get down to 12 stone."

Talking about her experience on the X Factor, Emma admitted: “I had good and bad from that show. The good thing is we did a show with you, lost weight, but then I had death threats and bullying online.”

Lorraine asked how she dealt with it and Emma said: ”I talked to family and friends and ignored them, I just blocked them. I still get negatives, people saying ‘You’ve had a gastric band.’ And I haven’t.”
