Paris Hilton’s younger sister Nicky Hilton is expecting her second child with husband James Rothschild. The fashion designer and her businessman husband are reportedly “thrilled” over their new bundle of joy.

On Thursday, a spokesperson for the couple confirmed to Us Weekly that Hilton is indeed pregnant. “The couple are thrilled about the new addition to their family,” the spokesperson added.

This is Nicky’s second pregnancy. She gave birth to their first daughter, Lily Grace Victoria Rothschild, in July of last year. The 33-year-old socialite-model is revealed to be three months along and is due to give birth to baby no. 2 in early 2018.

Over the weekend, Nicky attended Princess Olympia and Prince Pavlos’ joint 21st and 50th birthday party. At the Marie Antoinette-themed event, she rocked a corset so it was impossible for guests to know that she’s already pregnant, a source divulged.

It seems that Nicky’s second pregnancy has been well planned by her and her husband. An insider dished to Daily Mail that the husband and wife have always wanted to have kids who are close in age. “It’s Lily’s first birthday [on] July 8 so they are excited. They always wanted to give Lily Grace a sibling close in age, like they both have,” the insider said.

Hilton and Rothschild tied the knot in July 2015 in a lavish ceremony at Kensington Palace. They got engaged in August 2014 in Lake Como, Italy. The two started dating in 2011 after meeting each other at Petra Ecclestone and James Stunt’s Italy wedding. Hilton was previously married to financier Todd Meister, but she ended their relationship three months after their wedding in August 2004.

Speaking of how her daughter approaches motherhood, proud mom Kathy Hilton previously told People that she finds Nicky’s ways “unbelievable.” “With my babies, if I wanted to go pick them up I would just go in the room in the middle of the night, but Nicky is very much on a schedule. This is nap time, this is tummy time, so I’m just kind of like, ‘Okay,’” Kathy said. “I’ll tell her certain things, but she’s read up on everything.”

Meanwhile, Paris is said to be smitten with boyfriend Chris Zylka as of late. The hotel heiress appears to be very serious with the “Leftovers” actor that she’s willing to do anything just to be with him. “Now that I am in a serious relationship and my boyfriend has film projects, I can’t do the residency (in Ibiza) for the full five months,” Paris was previously quoted as saying by Page Six.
