Actor Nick Frost, known for his roles in the "Harry Potter" franchise and Edgar Wright's Cornetto Trilogy, has welcomed his fourth child with his partner, Hayley. The 54-year-old confirmed on the "Inside of You with Michael Rosenbaum" podcast that the couple now has a six-month-old baby.

Frost also hinted that he and Hayley may have quietly married, as he referred to her as his "wife" multiple times during the podcast. He stated, "My f***ing kids keep me young. I've got a six-month-old, one's four, one's eight, and I've got a big, big boy who's 15." Frost shares his eldest son, Mac, with his first wife, TV executive Christina Lesbirel, and his younger three children with Hayley. The name and sex of the new baby have not been disclosed.

Explaining the decision to have another child at his age, Frost said, "I'm 54 and as I was saying to Hayley, if we're going to do this... you know, I don't want to be like f***ing Pacino or Mick Jagger. I don't want to be that kind of dad." He referenced Mick Jagger, who was 73 when his son was born in 2016, and Al Pacino, who welcomed a child at 83 in 2023.

Frost described his home life as content, stating, "I'm happy being here with Hayley and my four kids. We put the kids to bed, and me and Hayley get into bed at eight o'clock and we have a cup of tea and we watch some kind of s***. We watch My 600-lb Life. And that's it. That's my life. And I f***ing love it."

Frost was previously married to Christina Lesbirel from 2008 until their divorce in 2015. He announced the arrival of his third child, his second with Hayley, in August 2021 via an Instagram post. His current relationship with Hayley has been kept private, with the couple having never been pictured together and Hayley's surname remaining undisclosed.

Frost's latest family news comes as he prepares for a significant role as Rubeus Hagrid in HBO's upcoming television adaptation of J.K. Rowling's "Harry Potter" series. He will be taking over the character previously portrayed by Robbie Coltrane, who died in 2022. The new series is scheduled to premiere on Christmas Day, with the first season adapting "Harry Potter and the Philosopher's Stone." Frost noted that the filming schedule allows him to remain actively involved in his children's daily lives, including school runs and extracurricular activities. "It's a really nice schedule if you have lots of children because there's a lot of time when I'm taking the kids to school and picking them up," he said. "We're going to Scouts, we're going to football. It's really conducive to have a family within."
