An Instagram star hit back at trolls who called her “flat chested”.

Madeleine Ang, known to her followers as Okokokmou, faced a barrage of cruel comments after posting bikini snaps from her holiday in Malaysia.

Pictures show her on Redang Island in the Malaysian state of Terengganu, where she stood with crystal-clear water behind her.

More than 43,600 people liked the post – but dozens of commenters used it as an opportunity to body shame the influencer.

One hater branded Madeleine a “small-boobie monster”, while another said: “Flat chest?”

And a third responder harshly said: “You are flatter than my grandma's flat-bottom pot.”

While many liked Madeleine's post, some used it as an opportunity to body shame her

Madeleine refused to let the trolls get her down.

On her Instagram stories, she defiantly said that she’s proud of her figure.

She wrote: “I have always considered myself having small breasts and known to be the 'ironing board' girl since I was a child.

"Not only that, but I am also very short and not particularly good looking, just like an underdeveloped child.

“But truth be told, I am very proud of myself. I am very happy because I get to do what I want to do. I am fulfilling my dreams and I am not hurting anyone in the process.

“As long as you are not hurting anyone, you should always be yourself."

Madeleine's fans praised her body confident attitude

Many praised the Malaysian influencer for her body confidence.

One responder gushed: “Very nice and sexy! I wish to be confident like you.”

Another said: “Nothing is more impressive than a person who is secure in the unique way mother made her. You go, awesome girl.”

And a third added: “I love your attitude. You have a cheerful outlook.

“If I see those online haters, I will help you report their comments.”
