Paris Hilton has stunned her fans by announcing she's secretly welcomed a child with hubby Carter Reum.
The socialite took to social media to make the announcement, showing a sweet snap of the tot's tiny hand gripping her thumb.
Paris, 41, captioned the upload: "You are already loved beyond words," before adding a blue heart emoji.
She has since revealed the tot is a boy and admitted it's a "dream to be a mother".
Famous pals flocked to the comments section to share well wishes and surprised messages. Among them was Chrissy Teigen, who also just became a mum again a little over a week ago.
The model wrote: "A BABY!!!!! congratulations so happy for you both!!"
Heidi Montag also penned: "Ahhh!!!!! Congratulations!!!!!!" while Barbara Corcoran said: "Motherhood- that’s hot! Congratulations mama!"
Speaking to PEOPLE, Paris said: "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."
No further details were shared about the new arrival.
The youngster is Paris' first child, while Carter, 41, shares a daughter, 10, with reality star Laura Bellizzi.
Paris has been open about her desire to be a mum in recent years. In December last year, she revealed the pair had began the in-vitro fertilisation (IVF) process during the Covid-19 pandemic.
She told the same publication: "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."
The latest arrival comes a little over a year after Paris and Carter tied the knot in a lavish wedding. The heiress said 'I Do' alongside the entrepreneur at her grandfather's Bel-Air estate in a stunning ceremony, surrounded by celebrity pals.
She wore an Oscar de la Renta for the occasion, with the dress featuring a high neck lace design with matching veil.
Posting on social media at the time, Paris gushed: "My forever begins today," before adding the hashtags 'just married' and 'forever Hilton Reum'.
Earlier on Monday night, Paris also revealed her new memoir is available to order, saying it reveals "some of my most personal and private experiences that I've never shared before".
She admitted she hopes that by sharing her story, she will be able to inspire others to also overcome "incredibly dark hardships".
