Benji Madden calls Cameron Diaz 'my Queen' in sweet birthday post
Madden also called Diaz the "greatest Mom" to their daughter Raddix.
Despite largely staying off social media while "working" and "doing family life," the Good Charlotte singer, 44, wrote in an Instagram post shared on Aug. 30 that he has "grown to like my little tradition of coming back on special occasions to show love to my Queen."
Alongside the post he included a photo of the "Charlie's Angels" actress cuddling a kitten.
"So today, it's a very Happy Birthday to my beautiful wife, best friend, best partner in everything, ride or die, greatest Mom to our little girl, @Avaline wine boss, family chef, advisor, collaborator and everything else," he gushed. "You do it all."
Elsewhere in the caption, Madden said he's "so grateful" for their family, including their 3-year-old daughter Raddix, and called himself "one lucky man."
"I know that seems obvious but it really is nice to say it out loud now and then when you're feeling it," he wrote. "I love you forever, always, yours, true love. Happy Birthday Cameron."
Diaz took to the comments section to respond to her husband's post, writing, "There's no one else I would rather do this life with. We are so blessed. I love you with all my [heart]."
Madden wasn't the only one wishing Diaz a happy birthday.
Gwyneth Paltrow also took to Instagram to wish her friend well on her special day, sharing a selfie of them together and, like Madden, calling her "my ride or die."
