Elvis Costello and Diana Krall Expecting First Baby

Diana Krall and husband Elvis Costello announced Sunday that the jazz singer is pregnant and due in December — just in time for their third wedding anniversary.

A spokesman confirmed the pregnancy.

Costello, 51, is touring with Allen Toussaint in support of their album, "The River in Reverse."

The veteran British rocker's songs include "Veronica," "Pump It Up" and "Alison." The 41-year-old Krall will release a new album this September.
