Mariah Carey, Nick Canon

It may seem like media staples Nick Cannon, 31, and Mariah Carey, 42, have been together forever, but they surprised the world when they tied the knot in a secret ceremony in the Bahamas on April 30, 2008, before anyone could even confirm they were dating, much less dating (though Carey was spotted wearing a giant engagement ring in late April 2008, which prompted rumors). Three years to the day after the couple wed, Carey gave birth to their boy-girl twins, Moroccan and Monroe, at age 41. “I’m just happy to be in love and to be here,” she told Barbara Walters last year.
