At the time, Cameron had also taken to Instagram to share the news to her followers by penning a message around New Year's. 

'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, Raddix Madden.' 

The actress continued, 'She has instantly captured our hearts and completed our family. While we are overjoyed to share this news, we also feel a strong instinct to protect our little one's privacy.' 

'So we won't be posting any pictures or sharing any more details, over than the fact that she is really really cute!! Some would even say RAD:)...' 

During an interview on The Tonight Show With Jimmy Fallon back in 2020, The Mask star opened up about how both she and Benji have fully embraced parenthood, adding that it's 'the best thing that ever happened' to them. 

"It's been heaven. Literally every single day, there are just leaps and bounds...and she's not the same baby that she was yesterday.' 

However, Cameron has also been candid about the difficulties of motherhood as well - and discussed the topic on The Kelly Clarkson Show back in 2022.

She gushed to Clarkson that being a mother is 'the best thing I've ever done in life' but revealed that she has a 'check list' for when times become a little 'challenging.'

'Did she eat? Is she tired? What time is it? When was the last time she ate? When did she nap? You just kind of start there, and you go, "What just happened? Is there something she's trying to communicate to me?"' Diaz explained. 

'And I feel like as a parent, my job is to just help her find the words to her emotions, her experience, what she's going through and be able to help her identify that and move through it.' 

The star added, 'But you know what's also really imperative to repair. Like if you do blow up, just to repair that and say, "Oh my God, mommy lost her s**t," And, "I didn't mean to say that to you."' 

'If I hurt your feelings or if I upset you, I just want you to know that mommy's human too.' 

Cameron initially retired from acting following her role in the 2014 film, Annie, but has since returned to star in Netflix's Back In Action alongside Jamie Foxx.

The pair were spotted earlier this year on set after the actor's recovery following a near-death health scare. 

The action comedy movie is directed by Seth Gordon and also stars Glenn Close, Andrew Scott as well as Kyle Chandler.

The plot synopsis of the project has remained mostly under wraps and a set release date has yet to be announced.

Earlier this month, it was also reported that Diaz was in final talks to work with Keanu Reeves and director Jonah Hill in a project called Outcome.
