It’s D-Day — as in Delivery Day — for Gwen Stefani! The singer checked into Cedars-Sinai Medical Center in Los Angeles and is scheduled to give birth via C-section at 10 a.m. PT. This will be the second child for Gwen, 38, and her husbandGavin Rossdale—and it’s in the same hospital where she gave birth to son Kingston, 2. “Gwen’s so excited to have this baby because she gained a lot of weight during this pregnancy,” her pal reveals to In Touch. “She is ready to meet her new baby and get her body back.”
