Sarah Harding admits having lip fillers was a "mistake".
The 34-year-old singer-actress underwent the cosmetic procedure in her late 20s but insists that's the only enhancement she has done to her features, reported Femalefirst.
"I don't understand what people think I've had done. I can smile, I can frown, everything on my face moves. I've dabbled with my lips in the past, but that was a mistake and I learned from it. The only thing I've had done is getting my eyebrows tattooed on," she said.
The former Girls Aloud star said the constant scrutiny of her appearance and lifestyle does upset her more than people realise.
"People don't know me, they see me and think, 'She's got a hard face'. They assume that because I look tough and I'm in the limelight, my feelings don't get hurt. But I'm still a human being and I have emotions just like everybody else - people forget that. I wear my heart on my sleeve and, although I try to ignore negative comments, they do get to me.
