Rap star and business mogul Jay-Z turns 42 on Sunday, and we're marking the special occasion with a look back at his sweetest moments with wife Beyoncé Knowles.

It's been a big year for Jay-Z, and if becoming a father wasn't exciting enough, he just earned his latest Grammy award nomination. From "Crazy in Love" to their latest collaboration with a baby on the way, Jay-Z and Beyoncé have been one of our favorite celebrity couples for 10 years strong. We're so excited to see what 2012 brings.

Happy birthday, Jay-Z — click "Launch Gallery" below to see their cutest pictures together!
