E! News host and reality TV star Giuliana Rancic was recovering Wednesday after undergoing a successful double mastectomy.

Rancic, 37, underwent the four-hour procedure Tuesday night as part of her battle against breast cancer.

"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."

"She had a little bit of pain through the night but is feeling much better this morning and was cracking jokes," he added.

Giuliana Rancic said earlier this month that she would undergo a double mastectomy after a lumpectomy did not remove all the cancer.

She was originally diagnosed with the disease when she saw a fertility doctor during her third attempt at in vitro fertilization, as detailed in the Style Network's reality series "Giuliana & Bill."
