It comes after Jelena attacked “body shamers”.

She posted striking pictures of herself in sizes 6 and 16, along with a lengthy caption imploring fans not to “judge” her.

“Are you going to judge me if I wear a size 16 because I'm a larger size?” began the athlete-turned-commentator.

“And would you judge me if I ever wear a size 6 again because I’m no longer bigger and maybe I’ve lost weight?”

“You shouldn’t. Either way,” Jelena added.

Jelena recently criticized “body shamers”. She posted striking pictures of herself in sizes 6 and 16, along with a lengthy caption imploring fans not to “judge” her.

“Shaming and making fun of someone because of their weight or judging their worth based on their size is pure body shaming and bullying,” the former world number four wrote.

“When it comes to health, of course I want to be healthy. Of course I do my best. Of course I'm working on myself.'

She added: “The takeaway is that we need to stop focusing on size, weight and measurements and focus on kindness, good hearts and generosity.”

“What if I wear a size 16 today and a size 4 later?” Who cares!'

“And last but not least: if you want to lose a few kilos, what then? If you gain some weight, what happens? There’s nothing wrong with one or the other,” Jelena concluded.
