BRIGITTE Nielsen said she has given birth at age 54.

The model, actress and reality star and her 39-year-old husband Mattia Dessi released a statement to People magazine Saturday saying their daughter Frida was born Friday in Los Angeles and weighed five pounds, nine ounces (2.3 kilograms).

It’s the fifth child but first daughter for Nielsen, who has four adult sons from previous marriages. She married Dessi, her fifth husband, in 2006.

In a statement, the couple said, “We are overjoyed to welcome our beautiful daughter into our lives,” and “it’s been a long road, and so worth it.”

Nielsen revealed her exceptionally late-in-life pregnancy last month by posting photos of herself lounging with hands on her belly on Instagram and Twitter, saying the family is getting larger. (AP)
