Cameron Diaz and Benji Madden are parents.

The couple announced in matching Instagram posts Friday that they've welcomed a daughter, Raddix.

Out of respect for the child's privacy, they did not share a photo of the baby or details of her birth.

"We are so happy, blessed and grateful to begin this new decade by announcing the birth of our daughter, Raddix Madden. She has instantly captured our hearts and completed our family," they wrote.

Diaz, 47, and Madden, 40, wed almost exactly five years ago in a private ceremony at their home in Beverly Hills, Calif. Although they have remained mostly out of the public eye since tying the knot -- the most recent image of the two together is from an Instagram post Madden shared in August, 2019 -- Diaz told Marie Claire in 2014 that she was open having children, but added it wasn't a priority at the time.

"We live in a society where everyone has kids, so they want other people to have kids. There is this culture that says celebrities are supposed to be just like us, so people think,'I have children, why doesn't she?' But I'm not going to do something because it's expected," she said. "If a family happens, then it happens. If children come to me, then I would do that, but I'm not someone who feels like she has to do something because it's expected."

While the new parents chose not to share an image of their daughter, they wrote they could share "the fact that she is really really cute!! Some would even say RAD:)"
