Sharing a picture of the pair cuddled up on a boat, Benji wrote that he feels lucky to have the actress as his wife. "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." Cameron and Benji married in 2015, and we don't think they could get any cuter.
