Nicky Hilton, born Nicholai Olivia Hilton, is expecting her first child with husband James Rothschild. An insider with knowledge of Hilton's pregnancy revealed the news to several news outlets.

People learned from a source that Hilton is "feeling great" with her pregnancy. The American fashion designer and heiress is said to be "very excited to become a mom" to Rothschild's child.

"They've just begun telling close friends and family. Nicky and James are over the moon!" the insider further told People.

Hilton and Rothschild are expected to welcome their first child in the summer, added E! News. The Hilton family is said to be "delighted" about the baby news.

The married couple were reportedly recently spotted at The Grove in Los Angeles. They were looking around at Pottery Barn Kids, further confirming the news of Hilton's pregnancy.

Hilton's baby news came six months after her fairy-tale wedding to Rothschild on July 10 last year. The couple married at England's Kensington Palace, which is the home of the Duke and Duchess of Cambridge, Prince William and his wife Kate Middleton.

The heiress' pregnancy also came after she admitted back in September that she is not yet ready to become a mom.

E! News caught up with Hilton during her September/October 2015 Fall Fashion show at the New York Fashion Week. When asked about her plans to start a family right away now that she and Rothschild are married, the 32-year-old sounded hesitant about having children.

"I'm just enjoying being married right now," she told E! News, although she admitted that she would love to have her own family someday in the future. Hilton also spoke about married life and said it feels "different" and "more grown up." Hilton likewise told E! News that she highly recommends marriage to people who find the right person that they want to spend the rest of their lives with.

Hilton was briefly married to Todd Meister in 2004 before meeting Rothschild. She and Rothschild were long-time couples before saying their "I dos" at Kensington Palace. They met in 2011 and became engaged in 2014. Hilton's sister, Paris, had once commented on how the pair is perfect for each other. Paris told People ahead of her sister's wedding that they are the "ultimate couple."

"They're so loyal and they're so in love," Paris said, adding that her sister and Rothschild are perfect for each other because they are "like prince and princess."
