Lisa Potter-Coyne, 29, a make-up artist, and husband Theo Coyne, 28, had jokingly posted an invitation to the RnB star on YouTube, and the spoof version of his hit song 7 Days quickly spread across the globe. The video was posted online in May and the couple were married at Ely Register Office on Friday, gathering at Lisas parents house in Witchford the following day for a party with friends and family. At about 9pm they were given the surprise of their lives, with the multi-platinum selling artist making the trip from his home in Los Angeles to make a special appearance. And the Southampton-born singer even took to the microphone to lead a singalong with Lisa, Theo and guests. Posting on Twitter, Lisa, who lives in London, said: Were still absolutely buzzing from the wedding! Still feels like a dream! So excited, we couldnt sleep! Craig wrote on social networking site Instagram: Had the most amazing experience surprising Theo and Lisa at their wedding celebrations! Seeing them so happy having me attend and hearing me sing was as emotional for me as it was for them! They told me how they have been fans of my music from the start of my career. They have bought all of my songs, been to over 25 of my concerts and that my music had brought them closer together over the eight years that they have been partners.
