As a member of last year's winning Britain's Got Talent act, Collabro, Jamie Lambert said it's important to "stand up and talk" about his past eating disorder.

The singer said he was bullied for being overweight, having acne and coming out as gay whilst at school, and claims to still experience cyber bullying from "people who use twitter as a weapon".

Jamie said despite his life now being "bright and shiny", he still struggles thinking about his weight, and said it is important to show the band's fans he is a "real person" who has "been through real things".
