Singer Nathan Sykes has revealed that performing live is one of the most exhilarating things he has ever experienced. 

When asked by BANG Showbiz reporters backstage at the Capital FM Summertime Ball to reveal the one thing he could never give up, Sykes had an easy answer. He said:

"Um...doing that. Performing for people - singing. To be able to say I've performed at Wembley Stadium seven times now in front of 80,000 people every year is just mind-blowing. It's what you dream of when you're growing up."

When asked if there's "anything going on" between himself and 'X Factor' winner Louisa Johnson, who joined him on stage for a duet on 'Over and Over Again', he was quick to shut down rumours: "Bringing Louisa Johnson out today... no, not at all! We've known each other for two days and her boyfriend's really cool as well!"
