Paris Hilton shares first pictures of newborn baby son, saying he has her ‘whole heart’

Paris Hilton has shared the first pictures of her baby son.

Hilton, famed for her business ventures and her reality shows such as The Simple Life, shared the black and white photographs to her Instagram page on Monday evening.

The four photographs show her cuddling her son, who is wearing a white outfit, complete with a hat.

She captioned the post: “My whole heart. #MommyMonday”.

Hilton and her partner Carter Reum had kept the birth of their child a secret, even from their closest friends and family, who they had via surrogacy.

Earlier in the year she revealed her son’s name, Phoenix Barron Hilton Reum, saying she wanted a name reflective of world cities, like her own.

Speaking on her podcast This Is Paris, she also explained she wanted a name with several meanings.

She added her life was now “complete”, describing her partner Mr Reum as an “angel and such an incredible father”.

“It’s amazing being a mum, it sounds so weird saying I’m a mum but I love it,” she said.

Hilton spoke to Sky News last month about alleged abuse at a so-called “troubled teen” boarding schools, which she famously attended, and has since campaigned against.
