In April 2012, the too-cute couple continued their tradition of renewing their wedding vows with a ceremony atop the Eiffel Tower. (Rev. Al Sharpton officiated on their third anniversary, shortly after their twins were born.) "Tonight was an incredible night," Mariah tweeted. "I can't express how amazing it was to renew our vows in Paris at the top of the Eiffel tower." The duo followed the ceremony -- and an extravagant shopping trip along the Champs-Elysées earlier in the day -- with dinner at Le Jules Verne restaurant on the Eiffel Tower.
