Latin diva Gloria Estefan will be performing at Wembley Arena this week, the night before Madonna plays Wembley Stadium. In an interview to the Mail Online she also talks about the good advice she gave The Queen Of Pop about having babies:

"Madonna was over to dinner and all we talked about was babies. My baby, the problems I'd had conceiving after breaking my back, the baby she wanted at 37 - the same age as I was with Emily. So I gave her two tips. One, have a pain-killing epidural injection. Two, if you want to help nature, get your legs in the air!" Gloria laughs.
