On Friday, Dec. 22, fashion designer Nicky Hilton took to Twitter to announce that she and husband, James Rothschild, welcomed a baby girl.

The socialite shared this tweet on Twitter:

The designer gave birth to her little girl on Wednesday, Dec 20. The couple already have a little girl, Lily Grace Rothschild, who will now be a big sister to Teddy Marilyn Rothschild. Teddy gets her name, Marilyn, from Hilton and her sister Paris Hilton's grandmother, Marilyn June Hawley. 

A rep told Us Weekly that the couple are thrilled about the new edition of their family. Hilton has definitely not been shy about sharing the excitement about being a mom to two little girls.

In September, Hilton opened up about her latest pregnancy with baby number two in an exclusive interview with Us Weekly.

"I feel great. I have more energy than ever," Hilton said.

While attending the New York City Ballet's 2017 fall fashion gala, Hilton explained that the couple decided not to learn their baby's gender in advance. Hilton explained that she knew the gender of her first child, but wanted to discipline herself with her second child. 

The "365 Style" author also revealed that she's a lot like expecting moms when it comes to cravings.

"I've been craving really random things like eggplant parmesan, hot tamales," the designer said.

Although Hilton had various cravings throughout her pregnancy, it didn't affect her weight as the socialite posted several stylish looks on her Instagram. Let's just say, the photos serve up major pregnancy inspo.
