Tulisa Contostavlos said she never let herself believe she was "finished forever" and "pretended I was fine" to survive the drugs allegations that threatened to destroy her career.

"And now I'm so comfortable in my own skin, I just went for it. I never intended to get fillers in my cheeks, but when it was mentioned to me I thought I'd give it a whirl."
