Paris Hilton has shared a selection of pictures of herself with her newborn son.
The American socialite and entrepreneur posted four black-and-white photos to her Instagram page on Monday, showing her cuddling the baby, who was born via surrogate.
"My whole heart. #MommyMonday," Hilton captioned the pictures.
In February, the former reality TV star revealed that her son's name is Phoenix Barron Hilton Reum.
Hilton and her husband Carter Reum had kept the baby's birth a secret from even their closest friends and family.
Hilton said she had wanted to choose a baby name on the theme of world cities - like her own first name.
Explaining the thought process behind the baby's name on her podcast, This Is Paris, she also said she had wanted one with multiple meanings.

Hilton added that her life now feels "complete" and praised 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.
