Nearly four years after their tying the knot in the Bahamas to the surprise of many, Nick Cannon dropped to one knee before wife Mariah Carey during a Parisian vow renewal ceremony atop the Eiffel Tower on Friday night.

In a photo shoot beforehand, the 42-year-old part-Venezuelan singer is shown beaming in a white mermaid dress with spaghetti straps and a black bow at the waist as Cannon, in a white suit and black tie, locks his eyes with hers.

“Tonight was an incredible night,” the singer announced via her Twitter account. “I can’t express how amazing it was to renew our vows in Paris at the top of the Eiffel tower.”

The couple—the proud parents of nearly 1-year-old twins—will officially celebrate their fourth anniversary on Monday, April 30.

The couple had arrived in France by private jet around 1:00 am on Friday. During the day, Carey was spotted shopping at Baby Dior – the couple’s twins turn 1 on Monday – and at the Louis Vuitton flagship store on the Champs-Elysees.

Friday night, after they posed for their wedding renewal photos, the couple was spotted dining at the Le Jules Verne restaurant on the Eiffel Tower.
