Jessie J later clarified her remark in a series of posts, saying: "To all the young girls commenting on my bikini picture. I am constantly trying to GAIN weight. And as a naturally slim woman At 5ft9 I am trying to be an example to any young girl similar to me that being stick thin is NOT good nor hot!"

She added: "I eat what I want in moderation! Too much fruit is not good beleeee that! I am not skinny I am slim. I have meat on my bones and I want more! I have never dieted but been healthy and aware that being fir it for life not for Instagram or looks! I work hard to be fit and it's not easy but it's IMPORTANT! For my career and for me! But everyBODY is different. What I have to do is different to what someone else would have to do to be HEALTHY! Let your aim to be strong and not a stick. To be happy and not skinny. And be healthy and BE YOU!"
