Just how many times does one couple need to say I do? Mariah Carey and Nick Cannon pile on the romance to renew their vows for the FOURTH time

They have already renewed their wedding vows three times, but Mariah Carey and Nick Cannon clearly haven't found enough ways to say 'I do.' The famous couple piled on the romance as they renewed their vows for the fourth time in front of the backdrop of the Eiffel Tower.

Mariah, 42, looked stunning in a fishtail white gown with a black sash which hugged her curves. The singer sported a chunky diamond necklace and matching earrings at the Parisian hotel, while her long light brown hair, was tied in a sophisticated half ponytail. And in a rather cheesy touch, husband Nick Cannon, 31, ensured he matched her in a white suit and black tie.

Rather unusually, the couple invited the press to witness their happy occasion at a photocall at the French capital's La Maison Blanche hotel. And Nick and Mariah showed how comfortable they were in front of the cameras, with Nick going down on one knee in a mock proposal. The couple wed at a private resort in the Bahamas on April 30, 2008 and like to celebrate by renewing their vows once a year.

They also mark the birth of their twins Moroccan Scott and Marilyn Monroe on the 30th, although the babies were kept out of sight today. The Precious star tweeted about the upcoming big day during her shopping trip this afternoon, writing: 'Shopping for Roc & Roe's bday in Paris...Dembabies dembabies dembabies!' She last week revealed the Cannon-Carey family will be celebrating big time, tweeting: 'We have put together some very festive plans: ) LYM! Can't wait to see you soon in Paris and Ischgl

Earlier the couple had looked equally lovey-dovey as they strolled around the city together. They shared kisses and held hands as they went shopping and sight-seeing in the City of Light. The diva couldn't resist flaunting the results of her 70 lb weight loss as she strolled around the city.

The Jenny Craig ambassador, whose svelte new figure graces the May cover of Shape magazine, wore a tight-fitting red and black lace belted mini-dress underneath an open black coat. Her ever-present oversized sunglasses rested on her face, while a matching pair of ankle strap heels adorned her feet. Her husband also looked dapper, though far more low-key in a grey turtle-neck sweater underneath his wool coat, and paired his red, black and tan suede trainers to match Mariah's shoes.
