The singer revealed that she was petrified during the early shows on the world tour, as she was convinced gig-goers would notice extra pounds she was carrying.
"I was pregnant when we talked about going back on tour. Then, of course, you don't really understand it - but once you have the baby...I was very self-conscious for maybe the first five or six shows. I just thought, 'How am I doing this? Three months ago I had a baby'," the Daily Express quoted her as saying.
"Jade pulled me to one side - and my mum - and both of them said 'Everyone knows you have had a baby, nobody is saying you have put a bit of weight on.' I just had to forget it all and enjoy the show, and that's what I did. At the time, I just panicked," she added.
