The Good Charlotte rocker took to Instagram on Saturday to wish his lady love a happy birthday, and it might just be the cutest thing we’ve ever seen from the usually very private couple.
"Happy Birthday to my beautiful Wife?, You're my best friend and I'm so thankful for you, sometimes I just want to tell the world❤❤❤," he wrote, alongside a pic of himself and Diaz at LACMA's Rain Room. "Generous, Kind, Compassionate, Selfless, Humble, Thoughtful, Patient and Loyal. Just a few of the qualities I would use to describe who you are, consistently, everyday."
"Thanks for being you, I'm a lucky guy❤," he concluded the post. "Here's to many more?❤ I love you❤❤❤@camerondiaz ????."
Just weeks earlier, it was Diaz who couldn't stop gushing about her husband.
"One of my favorite things about being married, is how much pride I take in my husband @benjaminmadden," she wrote on Instagram, along with a video of Madden performing. "He makes me proud everyday.. One day it might be how generous and giving, another how gentle and thoughtful. Or when he is fiercely protective of the people he love and cares about… And everyday single day I am so incredibly proud of his integrity as a human being."
Diaz and Madden, 37, tied the knot in an intimate ceremony in January 2015, after eight months of dating. While their courtship was short, Diaz couldn't be happier with married life.
"Someone asked me, 'What's your favorite thing about being married?' And I said, 'I just learn so much about myself. I didn't know these things. I would have never known them if I didn't have my husband to help me,'" the Other Woman star said during an appearance on The Ellen DeGeneres Show in May.
"I'm just so grateful for it because I couldn't do it without my husband, and I couldn't do it with anybody else except him," she added.
