Elvis Costello and his wife Diana Krall have something to sing about – they welcomed twins into the world last Wednesday. Boys Dexter Henry Lorcan and Frank Harlan James were born in New York City, according to a rep for the couple, who adds, “Mother and sons are doing splendidly.” The singers say, “We are ecstatic!” The babies are almost an anniversary gift for Diana and Elvis, who were married in London on December 5 three years ago. Diana revealed in September that she’s genetically disposed to a double delivery: “I have twins on my mother’s side as well.” She also declared she wouldn’t dress her kids up in matching outfits.
