And baby makes three! Heidi Montag gave birth to a baby boy, her first child with husband Spencer Pratt, on Sunday, October 1. The couple’s rep confirmed the news exclusively to Us Weekly. According to the site, the former Hills stars welcomed their son, Gunner Stone, just after 3pm.

“We are so blessed to have a beautiful healthy baby boy,” Montag told Us Weekly. “It was the hardest and most rewarding experience.”

Montag and Pratt first announced her pregnancy back in April. A few weeks later, they revealed they were expecting a baby boy. “It was in my heart to have a boy,” Montag told Us Weekly in May. “I thought Spencer really used to want a boy, and then a few months ago we had a conversation where he said, ‘Let’s just make sure it’s healthy. Boy or girl, I don’t care.'”

She added that she was “really excited” to see his personality develop. “I’m excited to take him to Disneyland and to see if he’s into dinosaurs, Mickey Mouse, or ballerinas — it can be anything. Maybe he’ll be the best dancer!” she told the magazine at the time.

In August, Pratt revealed that they had already chosen a name for their son — in part based on what social media handles were available. “We had to ditch a couple names,” he said on theAllegedly with Theo Von & Matthew Cole Weisspodcast.

He also joked that their baby would have an iPhone at birth. “I’m gonna teach this kid how to Snap when they’re born, like, ‘Put your finger here,’” he quipped on the podcast. “You walk around, everybody’s making their own content all day long. … I would just like my baby to be a professional content maker.”

Congrats to the growing family!
