Joel Madden is always gushing [2] about how amazing wife Nicole Richie is on social media, but on Saturday, the fashion designer flipped the script in honor of his 38th birthday. Along with a cute Instagram photo of the two at an amusement park, Nicole wrote, "Happy Birthday to my PIC @joelmadden 💛💛" Joel and Nicole are parents to kids Harlow and Sparrow [3] and have been married for six years now. From the looks of it, they're still crazy about each other [4].
