"G is doing really well," husband Bill Rancic told E! News
. "Her surgery lasted about four hours and the doctors were very pleased with the result."
The E! host, 37, decided to have a double mastectomy

"She had a little bit of pain through the night but is feeling much better this morning and was cracking jokes," Bill said.
While Giuliana recently told PEOPLE
