Paris Hilton and her husband Carter Reum’s newborn daughter’s birth certificate has been revealed, three weeks after they announced the birth of their second child.

In documents filed with L.A. County’s Vital Records, obtained by The Blast, the couple’s little girl’s full name is listed as London Marilyn Hilton Reum.

The birth certificate also confirms she was born on November 11, 2023, at 11:43 a.m. at Cedars Sinai Medical Center in Los Angeles.

The infant’s birth weight and height was not listed on the document.

London’s birthday falls on the lovebirds’ second wedding anniversary, and just ten months after her big brother, Phoenix Barron Hilton Reum, was born January 16.

Both London and Phoenix arrived to the world via surrogate, with Hilton and Reum, both 42, keeping both pregnancies under wraps, even from family and friends.

While Hilton revealed London’s first name and gender last month, she has yet to post any pictures of her baby girl.

The unusual moniker is no surprise as she actually decided on the name 10 years ago.

Talking on a live chat episode of her podcast back in March, she teased that she had picked out the name London if she ever had a daughter over a decade ago.

‘I’m really excited for Phoenix to have a baby sister one day—named London. It’s my favorite city and I’ve always wanted to name my daughter London,’ she said.

‘I had actually picked that name for a long time now, probably over 10 years. I always wanted London. I love that name for my daughter,’ she added.

She also told Ellen DeGeneres on her show back in 2022 that she had her daughter’s name planned.

She explained: ​​’The girl is gonna be named London Marilyn Hilton Reum.

‘Marilyn after my grandmother and London because it’s my favorite city and I think Paris and London sound cute together.’

Paris also wanted to keep the theme of cities running in her children, as her son is named after Phoenix in Arizona.

She previously said: ‘It was hard to pick (Phoenix) because a lot of the cities that I like just wouldn’t sound good as a name.

‘Like Ibiza would be so weird as a kids’ name, Vegas would be weird. It’s difficult to find a cool name that’s a city for a boy. Besides London, (because) that works for both,’ she said.
