Cameron Diaz has given birth to her first child, a girl, with her husband, Good Charlotte lead guitarist Benji Madden.

The news was announced via Cameron Diaz and Benji Madden's Instagram, confirming the rumours that Diaz was pregnant with her first child.

"We are so happy, blessed and grateful to begin this new decade by announcing the birth of our daughter, Raddix Madden," the post reads. It goes on, saying that for privacy reasons, that's all the details that the public are getting, other than the fact she's "really really cute."

Diaz retired from acting just two years ago and since her retirement, she has penned two self-help books and now seeing as she's going to be a mother for the first time, that'll probably take up a lot of her day.

Diaz met Benji Madden through her now sister-in-law, Nicole Richie. The pair married in 2015, having dated for ten months prior to the marriage.
