Cameron Diaz rang in her 45th birthday on Wednesday, and nobody gave her a more special shout-out than her husband, Benji Madden. The Good Charlotte rocker posted a photo of them cuddling on a boat under a blanket on Instagram, writing, "Happy Birthday to my Beautiful Wife ❤️ I feel like I am the LUCKIEST guy ALIVE❤️ I don't think anyone could ever know the Depth, Kindness, and Compassion that I get to experience everyday thanks to My One and Only- You got me til the end baby❤️❤️❤️" The adorable message isn't the first time Benji has spoken out about his love for Cameron. After the two tied the knot in a secret ceremony in 2015, he's made gushing about his wife on Instagram somewhat of a tradition, especially on her birthday. He made our hearts melt back in 2015 and again last year when he celebrated Cameron's special day. We love how in love these two are!
