Paris Hilton has hit back at her son’s critics after they mocked the baby when she shared a new family photo on social media.

On Friday, the new mama surprised her fans as she shared a series of photos in which she was seen smiling while posing with the infant.

While the businesswoman and media personality quickly received lots of positive comments, some people took the post as an opportunity to mock the innocent child over the size of his head.

Furious Hilton has since hit back at the trolls and reassured everyone that her baby was perfectly healthy.

“There are some sick people in this world. My angel is perfectly healthy. And yes, of course he has been to a doctor, he just has a large brain,” she wrote.

The comment comes shortly after Paris gushed about being a mom as she the word mother her favorite title ever.

“Moms are superheroes. I love being a mom so much,” she said.

Speaking of her little bundle of joy, she added: “Phoenix is such an angel. He just turned 9 months old.

“He’s getting so tall. He’s about to crawl soon, so it’s just so much fun seeing all these milestones.”

Hilton also paid tribute to her loving husband whom she branded as a romantic man full of “amazing surprises.”

The news comes after the socialite surprised her fans with a bombshell memoir in which she opened up about private matters such as the time she had an abortion when she was just 22. The memoir is now being made into a TV series.

“I’m just really proud of my memoir and that it touched so many people. And now to see it being turned into a TV series is pretty iconic,” the 42-year-old said.
