Cameron Diaz and Benji Madden announce birth of a daughter

Cameron Diaz and Benji Madden welcome Baby girl. 

 Cameron Diaz and Benji Madden are new parents. 

The couple shared the happy news on their official Instagram accounts with the same post. 

"Happy New Year from the Maddens! We are so happy, blessed and grateful to begin this new decade by announcing the birth of our daughter, Radix Madden," their note read. "She has instantly captured our hearts and completed our family." 

The joyful announcement came with a privacy caveat — and no photos, which has become a common practice among celebrities in recent years. 

“While we are overjoyed to share this news, we also feel a strong instinct to protect our little one’s privacy,” they added. “so we won’t be posting pictures or sharing any more details, other than the fact that she is really really cute!! Some would even say RAD :)” 

The new parents didn’t elaborate regarding the meaning of their little one’s moniker, and internet searches appeared stymied by the name. A variation of Raddix — radix — is a mathematical term for the basis of a system of numeration. It also can mean the source, origin or root of something. 

The “Charlie’s Angels” star, 47, and the Good Charlotte rocker, 40, wed in an intimate backyard ceremony at their Los Angeles home in 2015. 

Diaz, a greatly in-demand actress of the 1990s and early 2000s, starred in a slate of memorable films early in her career, including “There’s Something About Mary,” “My Best Friend’s Wedding,” “The Mask” and “Being John Malkovich.” She last appeared in a batch of 2014 films, including the musical “Annie,” the comedy “Sex Tape” and the rom-com “The Other Woman.” 

“It’s funny, because [Benji’s] brother is Nicole Richie husband and when they named their kids Harlow and Sparrow, those names seemed so outrageous when they picked them, but a lot of people imitated them,” Redmond says. “So those names got popular.”
