Kylie Jenner admitted she's gained weight in a bid to stop online bullies commenting on her curvier figure.

The 'Keeping Up With The Kardashians' star shared a photo of herself in a revealing black swimsuit on her Instagram account earlier today (16.05.15) which left very little to the imagination.

She captioned the image: ''behind the scenes. (yes I gained weight there I said it so u don't have too) :). (sic)''

However, the 17-year-old star quickly changed her mind about the admission and edited the caption to simply read: ''behind the scenes.''

Kylie's decision to be open about her figure comes just a couple of weeks after Selena Gomez fell victim to online bullies who taunted her about her alleged weight gain after she posted a picture of herself in a similar revealing swimsuit online.

The 22-year-old beauty was quick to slam her critics and hit back at one ''disgusting'' Instagram user for urging her to ''work out'' and ''please stop eating junk food.''

The 'Come & Get It' hitmaker responded: ''IM IN the business and I could care less about what 'they' or you said I should look like. I don't need to do anything other than love myself, take care of my work, fans, family and friends...And I do work out. It's not your place to tell anyone what they should or should not do.''
