Pregnant jazz star Diana Krall is being urged to slow down by friends and family, four months before the birth of her first child. The Canadian singer and husband Elvis Costello are looking forward to the birth, but Krall admits she hates doing nothing for nine months. She says, "Now I'm having my own family which is freaking me out. "I've just been on an incredible tour... oh my God, I'm pregnant on top. "One night we were swinging really hard and I was thinking, 'How's this for the baby?' And JOHN CLAYTON (bassist) says, 'What are you gonna do? Swing him to death?' "Then I'm thinking I should be going to yoga classes, but playing and singing every night is probably a really good thing because you are doing the breathing and expressing all these emotions. "(It's time to slow down) even if I wasn't having the baby."
