Paris Hilton has announced she and her husband Carter Reum have welcomed a child together.
The A-lister kept the bub very much on the down-low, however she has left social media shocked with a post on Instagram.
In the photo, Hilton's perfectly manicured fingers are wrapped around her newborn baby's tiny little hand.
"You are already loved beyond words," Paris wrote in a caption alongside the image.
She also added a blue heart to the post, which has lead many to suspect the baby is a boy.
People have flocked to the comments section to congratulate the couple on their new arrival.
Chrissy Teigen wrote: "a BABY!!!!! congratulations so happy for you both!!"
Elle Fanning added: "CONGRATULATIONS! Most beautiful mommy."
Real Housewives of Beverly Hills star Dorit Kemsley said: "Congratulations!!!! So happy for you!!!"
No details of the baby's name have been revealed, so we'll have to wait for that update.
Everyone has been wondering how Paris welcomed the child considering she never had a baby bump.
She and Carter embarked on an IVF journey at the 'height of the Covid-19 pandemic', according to WHO Magazine.
Paris told People: "We started going and doing it like a few months in because the world was shut down.
"We knew we wanted to start a family, and I was like, 'This is perfect timing. Usually, I'm on a plane 250 days out of the year, and let's just get all of the eggs stocked and ready,' and we have tons of them just waiting."
They married in late 2021 and Paris has since confirmed they used a surrogate for their first child together.
She explained to People: "It's always been my dream to be a mother and I'm so happy that Carter and I found each other.
"We are so excited to start our family together and our hearts are exploding with love for our baby boy."
