Chrissy Teigen has hit back at trolls and social media posts telling her she had her third child, Esti Maxine, via surrogacy.

The mother-of-three, who also shares Luna, seven, and Miles, four, with husband John Legend has posted an intimate photo showing the birth of her youngest via C-section.

Baby Esti was welcomed in January, and Chrissy, 37, has since been documenting her adorable family’s special trips and hilarious moments.

Earlier this week, Chrissy had written ‘obsessed with this comment’ over one troll’s post, in which – according to reports – it was written that she was ‘born male’ and ‘used something called a moonbump’ during her pregnancy.

The social media user is also said to have also insisted they were a ‘huge fan’.

Now, Chrissy has hit back with an intimate picture of Esti’s birth.

‘Extremely realistic “moon bump”,’ she wrote, over the hospital picture, in which Chrissy was looking up to see her baby being held by doctor mid-surgery.

All Of Me singer John has been full of praise for wife Chrissy since she gave birth for the third time.

In an interview last month, the award-winning star spoke of how it felt to expand their family once more and how everyone had been coping with their new addition.

‘There’s still a lot of recovery, but she’s doing great with it,’ he began, updating on Chrissy’s progress.

‘She’s so smart and strong and women go through a lot to bring life into the world and I’m always in awe of her for that.’

‘[It’s] very exciting,’ he told People Magazine of their packed household. ‘I was just saying my kids are doing so well. My older kids are doing so well with her and (it) just fills the house up with more love.

‘I just think we’re more comfortable with ourselves and our parenting style and I think we’re just more comfortable being parents now.

‘So, dare I say, it’s easier.’

Chrissy announced she was pregnant in August 2022, two years after she and John suffered the devastating loss of their baby, Jack.
