Giuliana Rancic's double mastectomy operation yesterday was a success.

The television host's husband Bill, told her network E! News that everything had gone well and his wife was in good spirits after the surgery.

Bill said that Giuliana is resting after the procedure and is "doing really well."

"Her surgery lasted about four hours and the doctors were very pleased with the result," Bill revealed.

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

Giuliana also sent her own message to her supporters to say how thankful she was for everyone's messages.

"I want to thank all the viewers and fans for their support and prayers," she said. "The tweets and notes have not gone unnoticed. I am very grateful."

The 36-year-old was diagnosed with breast cancer in October and after a lumpectomy was unsuccessful she decided to go for the surgery to drastically reduce the chance of the disease ever coming back.

Giuliana's cancer was caught early because her fertility doctor advised her to undergo a mammogram before going for her third round of IVF treatment in a bid to have a baby.
