The Hilton family is about to expand!

Nicky Hilton Rothschild is pregnant with her first child, according to People. An insider told the magazine that Paris' younger sister "is feeling great," and shared, "Nicky is very excited to become a mom."

The heiress married banker James Rothschild at a glamorous, fairy tale ceremony at Kensington Palace in July 2015, wearing a beautiful gown by Valentino. Like the wedding, the couple also had a beautiful courtship. The pair started dating 2011, and got engaged while boating around Lake Como in August 2014.

In advance of their new arrival, Nicky and James were spotted shopping at Pottery Barn Kids at The Grove in Los Angeles. Sources close to the Rothschilds say they're both ecstatic to expand their little family, claiming, "They've just begun telling close friends and family. Nicky and James are over the moon!"

Congratulations, Nicky and James!
