Paris Hilton is a mom, two times over.

For her next surprise, she added a daughter to the family just months later.

“The girl is going to be named London Marilyn Hilton Reum,” she declared.

Beyond the city theme, London’s first middle name, Marilyn, has two very special meanings.

Hilton chose the name “Marilyn” in honor of her grandma Hilton.

“She was charismatic, fun, full of life, and had a heart of gold.”

“I’ve always loved Marilyn Monroe since I was a little girl,” she toldCBS News.

“I think she’s such an icon.”

The name Hilton was famous long before “The Simple Life” star joined the clan.
