The rocker shared a picture of a fresh tattoo via Instagram on Monday, which features the name "Cameron" displayed across his already-inked chest.
"Thinking bout you❤️❤️❤️ #LuckyMan," the 35-year-old captioned the candid snap.
Clearly, the Good Charlotte musician's tattoo is a tribute to the gorgeous "Sex Tape" star. The cute couple secretly tied the knot -- after less than a year of dating -- in January in a private ceremony held in Beverly Hills.
"We couldn't be happier to begin our new journey together surrounded by our closest family and friends," the couple said in a statement to People magazine.
Things have definitely moved fast between Madden and Diaz, but it does seem like they're both pretty head-over-heels for each other.
