Benji Madden celebrated 'beautiful wife' Cameron Diaz's 45th birthday by posting an uber sweet message on social media.
"Happy Birthday to my Beautiful Wife," he captioned the Instagram picture, which shows him laughing with the ' Charlie's Angels' star on a boat ride.
"I feel like I am the LUCKIEST guy ALIVE. I don't think anyone could ever know the Depth, Kindess, and Compassion that I get to experience everyday thanks to My One and Only-You got me til the end baby."
The ' Good Charlotte' rocker and Diaz tied the knot in January 2015 after seven months of dating.
