Nicky Hilton is sharing a look at her new son.

On Thursday, Hilton, 38, took to Instagram and shared an image of herself with her two-week-old son laying on her chest. "Baby bliss," she captioned the image of the mother-son duo.

The fashion designer was lounging on a hammock while her son – whose name hasn’t been shared yet – rested in a white long-sleeve onesie that featured angel wings on the back.

Hilton and her husband, James Rothschild, announced the third addition to their family on Instagram on July 5. "We are officially a party of 5! Welcome to the world sweet boy. Mom, dad and big sisters could not be more smitten," she wrote alongside an image of the couple.

"We cannot wait for that," she told Fox News Digital of wanting to have kids. "We talk about it every single day. I’m just trying to figure out the time in my schedule because I have so many projects happening, and I just launched my media company, 11:11 Media. So there’s a lot happening, but that is definitely one of my top priorities."
