British pop star Jessie J is set to make one happy couple's big day even more memorable when she joins them to celebrate their nuptials on Friday (19Jul13). The bride and groom-to-be booked their wedding reception at Durham County Cricket Club in England 18-months ago but were stunned to discover that the venue had been double booked for a performance by the Domino hitmaker. Future bride Samantha Slater told local paper The Chronicle, "About two months ago they (staff from the cricket club) phoned us and asked us to go in. We thought 'What’s gone wrong now?'... they said another department had booked the concert and it’s the same day as the wedding. "We weren’t very happy about it at first, but when we found out it was Jessie J we perked up a bit. In fact, we were ecstatic." The singer is due to perform at the venue in front of a 15,000 strong crowd as the headliner for the Durham Summer Nights programme and has promised to take time out of her busy schedule to call in on the newlyweds for their first dance. She added, "I can't wait to be part of Sam and Chris' big day. It's going to be special. Bring on the first dance."
