Paris Hilton has revealed the name of her first child.

In an Instagram post on Wednesday, Hilton announced that she and husband Carter Reum named their son Phoenix.

"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 began. 

"Phoenix has a few good pop culture reference points but more important, it's the bird that flames out and then rises from the ashes to fly again. I want my son to grow up knowing that disaster and triumph go around and come around throughout our lives and that this should give us great hope for the future."
