Nicky Hilton has given birth to her second child with husband James Rothschild.
The hotel heiress, 34, and the British banking heir, 32, welcomed a baby girl named Teddy Marilyn Rothschild into the world in New York City this week, the Daily Mail reported.
Announcing the news via her Twitter page on Friday morning, Nicky wrote: "Christmas came early! On December 20th James and I welcomed a baby girl, Teddy Rothschild into the world. Feeling very blessed this holiday season."

Marilyn was the wife of Nicky's grandfather Barron Hilton, now 90 - the son of famed hotelier Conrad Hilton, who founded the Hilton Hotel empire. She passed away in 2004 at the age of 76 and raised eight children with Barron.
Teddy will be a little sister to the couple's daughter, Lily-Grace, 17 months.
Nicky's Los Angeles-based family flew into New York in anticipation of the arrival, with big sister Paris Hilton, 36, pictured arriving at JFK Airport on Wednesday with her actor boyfriend Chris Zylka, 32.
Paris appeared besotted with the family's latest arrival as she took to her Instagram page on Friday, saying she was 'so proud to be an aunt again' to 'beautiful little angel' Teddy.
Alongside a shot of Paris and Nicky as children, she wrote: "Feel like a kid on Christmas morning! So proud to be an aunt again! She is such a beautiful little angel! Welcome to the world Teddy Rothschild!"
Nicky was pictured running errands in Manhattan on Tuesday, showing off her baby bump in a red and black striped knit, while keeping cozy in a simple black wool coat.
The fashion designer recently said she and James won't be finding out the gender of their little bundle of joy, but she insisted she would be 'thrilled with either'.
Nicky told US Weekly: "You know what? I would be happy with either but I love having a sister.
"With a sister, you have a best friend for life. But a boy would be really cute, too. I'm thrilled with whatever."
The heiress also admitted little Lily has no idea she is about to become a big sister, but she's been helping her prepare for the new arrival by introducing her to the world of babies with a new toy doll.
Nicky said: "I bought her a doll and she loves her doll. It's her baby and it goes everywhere with her.
"She feeds her baby a bottle. She tried to put her baby in the bath with her tonight."
DailyMail.com exclusively revealed Nicky was expecting her second baby this summer.
An insider claimed she and sister Paris love being close in age, so the family are all very excited at the news.
"It's Lily's first birthday July 8 so they are excited," the source revealed. "They always wanted to give Lily-Grace a sibling close in age, like they both have."
Nicky has previously described being a mother to Lily Grace as 'heaven'.
Speaking to E! News in September 2016, she said: "I love it! I love it! Waking up to that face - it's heaven."
The Hilton hotel heiress married British banking heir James in a lavish ceremony at the Kensington Palace Orangery in London in July 2015, surrounded by the creme de la creme of British society, as well as their friends and family.
Nicky and James started their relationship in 2011 after meeting at Petra Ecclestone and James Stunt's Italian wedding.
James flew from England to the States to ask her parents for her hand in marriage before he proposed to her in Lake Como, Italy, in August 2014.
Nicky was previously wed to financier Todd Meister, before having the marriage annulled less than three months after they tied the knot in Las Vegas, Nevada, in August 2004.
