Paris Hilton revealed this week how she came up with Phoenix Barron Hilton Reum as a name for her son.

Hilton and husband Carter Reum welcomed a baby boy in January. Their son was born by surrogate.

On her iHeart Radio podcast, “This is Paris,” Paris Hilton revealed how she came up with the name years ago.

“If all goes well, by the time you read this, Carter and I will have a baby boy,” she read from her upcoming memoir, “This is Paris.” “We plan to name him Phoenix, a name that I decided on years ago when I was searching cities, countries and states on a map looking for something to go with Paris and London.”

Hilton is the great-granddaughter of Conrad Hilton. His son, Barron, was her grandfather. Hilton’s brother is Barron Hilton II.

“He was always my mentor. I looked up to my grandfather so much, and we were so close, and I miss him every day,” she revealed later in the podcast. “So, I really wanted to honor him by having his name in my first son’s name. So there you go. My beautiful baby boy’s name is Phoenix Barron Hilton Reum.”

“It’s always been my dream to be a mother and I’m so happy that Carter and I found each other,” she told People. “We are so excited to start our family together and our hearts are exploding with love for our baby boy.”
