The super hip Elvis Costello and his wife, Diana Krall, are expecting twins.
Krall told People, "Today I'm at six months. And you know, I'm having twins! I'm not kidding!" Elvis, 51, and Diana, 41, know the sex of the twins but aren't revealing the information. Krall says, "We know, and everyone's been asking me, but we're keeping that private because we just want to have something for ourselves." She isn't surprised about getting two-for-one, "I have twins on my mother's side as well."
The twins are due in December.
