NEW YORK — Mariah Carey is going to be a mom twice over.

Nick Cannon announced on his radio show recently that his wife is expecting twins.

Said Cannon on New York’s 92.3 station: “I haven’t even told my wife I doing this, so I’m probably gonna get yelled at for not getting permission. … We are having twins!”

Carey, 40, and Cannon, 30, have been the subject of a baby watch since they got married two years ago.
