Nicky Hilton has a mini me on the way!

On May 9, gushing aunt-to-be Paris Hilton revealed that her sister will be having a girl this summer.

"I'm so excited for the baby," Paris told Us Weekly in New York. "She's going to be such a beautiful little girl, and I can't wait to meet her."

Paris, who recently split with her millionaire man Thomas Gross, revealed how Nicky and her husband James Rothschild are preparing for their little one.

"They've been getting the nursery ready so I've been going to all the baby stores," Paris said, adding that she has already started spoiling her niece. "Now that I know it's a girl, it's getting easier to buy things for her. I love all the dresses I got her. There are so many beautiful dresses and little princess outfits. So I can't wait to see her in them."

Paris said she's also already offered up her sisterly duties to the couple when the little tyke arrives.

"I'm just excited to meet her! And just do aunt things," the heiress/DJ said. "I've never been an aunt so it'll be something very new for me, and I love babies so I can't wait just to see her."

It was announced in January that Nicky and James were expecting and that both were over the moon about the baby news.

Next up, other than the actual birth, of course, is naming the baby. But, don't look to Paris for help on that one.

"My favorite name for a baby is London, but that's for my baby! For her, I don't know. I can't really think of a name," she said.

Nicky is expected to have a baby shower next week in Los Angeles. If the shower is anything like her wedding, it will be a spectacle for sure.

The pair started dating in 2011, and got engaged while boating around Lake Como in August 2014. A year later, in July 2015, the couple was married in a lavish wedding at Kensington Palace.
