"She's so tiny right now you can't even tell [she's pregnant]," Paris said about her sis. "Usually you can tell with the size if it's maybe a boy or girl, but we have no idea -- and they want it to be a surprise."

The former reality star claimed that she was excited to become an aunt. "I am so excited. I can't wait to be an aunt -- my sister is thrilled," Paris added. This will be Nicky's first child with her husband, James Rothschild. The couple tied the knot at Kensington Palace in London last summer.

Nicky wore a white lace gown to the amfAR gala; her barley-there bump was visible in the snapshot she posted on Instagram.

Big sister Paris has been living in Switzerland with her boyfriend, Thomas Gross.  Paris told E! News, "I just feel like I'm in a different place in my life. I live in Switzerland now. I'm in love," she said. "I don't know, I finally feel like myself. It's exciting. [I'm] genuinely happy."

Paris said she'd be leaving New York early to get back to her beau for Valentines Day on Sunday.

"I just flew in last night from Switzerland, so I'm going to be going to a lot of shows, and then I have to rush back for Valentine's Day to Switzerland," Paris explained. "My boyfriend's taking me on a surprise trip somewhere for my birthday and to celebrate our first Valentine's together. He said, 'Pack bikinis.' We're going to land somewhere tropical and beautiful and some place I've never been before, so I'm excited. I love surprises."
