Nick Cannon, Mariah Carey

Before anyone could even confirm Mariah Carey and Nick Cannon were engaged (she was spotted wearing a giant engagement ring in late April 2008), the two announced they had gotten hitched in a secret ceremony at Carey’s Bahamas estate on April 30, 2008. Though they had met back in 2005, the couple only began dating the month before and hadn’t yet revealed the nature of their relationship prior to marrying. “I don’t think anyone realized what we already knew – that we were going to get married,” Carey told People magazine in May 2008. Carey and Cannon are now parents to 16-month-old twins, Moroccan and Monroe.
