She revealed they have named their newborn daughter Raddix Madden but noted they ‘won’t be posting pictures or sharing any more details, other than the fact that she is really really cute’.
The notoriously private star was pictured looking slim in high-waisted jeans on November 22 while out for lunch in LA, which suggests the pair used a surrogate or adopted.
She wrote on Friday: ‘Happy New Year from the Maddens! We are so happy, blessed and grateful to be this new decade by announcing the birth of our daughter, Radix Madden.
‘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’s one’s privacy. 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 couple was first linked in May 2014 when they started spending quality time together both at her home and the gym.
A source told People, “They’ve spent a lot of time at Cameron’s house. Cameron seems very happy with Benji. He is the nicest guy and treats her like a lady.”
“They seemed very friendly and they looked like they were trying to avoid [being seen outside],” said another source. “But Cameron was super friendly with other people [at the gym]. She even taught a girl how to use one of the arm weight machines.”
The duo became man and wife in front of 100 guests at Diaz’s Beverly Hills home in 2015.
“We got married in our living room in front of our friends,” she revealed on Radio Andy. “Had a little party in our backyard on the tennis court and yeah. Otherwise, it would have been something else.”
This past August, Diaz opened up to InStyle magazine about her marriage.
“My husband’s the best,” she said. “He’s the greatest human being, and he’s my great partner. Marriage is certainly hard, and it’s a lot of work. You need somebody who’s willing to do the work with you because there’s no 60-40 in marriage. It’s 50-50, period. All the time.”
