Mariah Carey and her 'loverboy' Nick Cannon – a whirlwind romance

The proud parents marked their fourth wedding anniversary – and the twins' first birthday – on top of the Eiffel Tower. Nick again got down on one knee in front of Mariah, who was dressed in a beautiful white mermaid gown and a black bow. "Tonight was an incredible night," the superstar singer tweeted. "I can't express how amazing it was to renew our vows in Paris at the top of the Eiffel Tower."
