Who says that you just have on wedding day in your life – Mariah Carey and Nick Cannon clearly don’t agree with that. The couple have been spotted looking all loved up after re-newing their vows again over the weekend. It is 4 years since their first big day – which they spent in the Bahamas – and their most recent ceremony was the top of the Eiffel Tower in Paris. They hired out the very top for their vows and left the tower looking sickeningly like they’d just got married for the first time. They renew their vows close to their wedding anniversary every year. Last year, as it coincided with the birth of their twins, they re-newed their vows in the hospital. It doesn’t matter where they are, they have to do it. After their latest celebration, Mariah got on twitter and said: “I can’t express how amazing it was to renew our vows in Paris at the top of the Eiffel Tower. Thank you so much to all the fans who came out as always and showed their love and support. I love you!” Nick said: "We get married every year; it's our thing. I just have to keep doing it to make sure it's real!" Nick also mentioned the 1 year birthday of the couple’s twins Morocco and Monroe, and revealed that they have big plans for celebrations – well, we expected no less Nick to be honest. He said: "It's up in the air right now but it's probably not going to be in the States. We are going to take it overseas." What lucky 1 year old they are. Do Mariah and Nick not realise that their children are probably too young to appreciate such a big gesture for their birthday.
