Nicky Hilton Rothschild is celebrating the birth of her first child with husband, and British banking heir, James Rothschild.
The baby girl was born in New York City on Friday, according to E! News.
The proud new parents have avoided the celebrity trend of bestowing an unusual name on a newborn. Instead, the new heiress has been named Lily Grace Victoria.
The 32-year-old socialite and fashion designer did not reveal too much information about her pregnancy. It was her older sister Paris, 35, who first spilled the beans about the baby's sex.
"I'm so excited for the baby. She's going to be such a beautiful little girl, and I can't wait to meet her," Paris said.
Nicky and James began dating in 2011 after meeting at a society wedding in Italy.
They married at Kensington Palace four years later. The bride wore a white Valentino haute couture wedding dress.
Guests included Chelsea Clinton and her husband Marc Mezvinsky.
