Only two weeks have passed since Giuliana Rancic underwent a double mastectomy and reconstructive surgery for breast cancer, and already the E! News host is in great spirits.

The 37-year-old beauty and her hubby Bill Rancic greeted fans at Santa Monica Place to sign copies of their book "I Do, Now What?" ... dishing advice on how to have a happy marriage.

Giuliana is now back at work alongside Ryan Seacrest. Rancic recently told her fans:

"It feels great to be back at work. I wasn't sure whether I was going to return to E! News this week or after the new year. The last thing I wanted to do was rush my recovery. Thankfully, I've been feeling better every single day since surgery and this weekend my doctors gave me the green light to get back to work."

What a great way to end a very tough year!

Giuliana Rancic underwent a successful double mastectomy and reconstructive surgery last night for her breast cancer, according to E! Online.

Husband Bill Rancic told the site, "G is doing really well ... 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." Giuliana added, "I want to thank all the viewers and fans for their support and prayers. The tweets and notes have not gone unnoticed. I am very grateful."

The E! News host was diagnosed with breast cancer three months ago, and she recently told The Today Show's Ann Curry that after some careful consideration, the radical procedure was the only option for her. "For me, it was important to get the cancer out," she said. "That's what I wanted to do, just get it out ... At the end, to be honest, all it came down to was just choosing to live, and not looking over my shoulder for the rest of my life."

Guiliana Rancic is speaking out on her upcoming double mastectomy and reconstructive surgery. The E! News host was diagnosed with breast cancer three months ago.

The 37-year-old TV personality tells People:

"My breasts have never defined me – and now they never will."

Rancic's surgery is scheduled for December 13. She adds:

"I think scars tell such an incredible story. I'll always look at them and think, 'Wow, I made it through that. Usually it's 2 in the morning, and I'll turn around from Bill so I don't wake him up, and I just cry. I sob and think, 'How did this happen?' "

Stay strong, G!

TV personality Giuliana Rancic will have a double mastectomy and immediate reconstruction, she announced this morning on The Today Show.

Giuliana and her husband Bill Rancic chatted with Ann Curry and revealed that after some careful consideration, this was the only option for them. "For me, it was important to get the cancer out," the E! host said. "That's what I wanted to do, just get it out ... At the end, to be honest, all it came down to was just choosing to live, and not looking over my shoulder for the rest of my life." Rancic was diagnosed with breast cancer back in October, and she is set to have the procedure next week.

Rancic said her husband's support helped her make the decision to have both of her breasts removed. "Bill said to me, 'I just need you around for the next 50 years, kid,'" she said. "He said, 'I don't care what you look like, I don't care about the physical portion of this.' And that certainly helped me come to a decision." She added, "I couldn't be more at peace with the decision. But it's hard, and I still break down some nights ... But I'm okay."

"Am I scared? Yes. Scared of the unknown. Scared of the pain," Rancic confesses. "But I'm not scared of what I'll be like. I'll have scars, but I like scars. Scars are beautiful because they tell a story. I'll be able to say that I survived something major and it's made me stronger. I will be a better woman for it."

E! personality Giuliana Rancic, 37, announced Monday morning that she has breast cancer.

The reality star and host revealed on Today that doctors discovered the cancer when giving her a mammogram as part of IVF treatment -- Rancic has been public with her multi-year struggle to get pregnant. She said of the discovery:

"It was just a kick in the stomach ... I was just a few days away from going to Colorado to get IVF ... It was incredible, instant sobbing ... 36 years old, no family history ..."

Rancic said she must undergo surgery and six weeks of radiation therapy, but that because the cancer was caught early, her prognosis is good. She will then continue her quest to become pregnant.

"I still want this baby ... this baby has saved my life. I truly feel God was looking out after me … If I had gotten pregnant later down the line, I could have been a lot sicker."

Rancic was visibly shaking through her emotional interview with Ann Curry -- watch above.

As for who is doing the injecting, Guiliana, 36, says, "Bill could honestly be on Grey's Anatomy. He could be McRancic."

Bill, 39, who says the couple's miscarriage was hard on their marriage, recently told Popeater.com:

"We took a much needed break from all the fertility stuff to connect with each other again. We had been trying for so long to have a child that the whole process had consumed us. A break was crucial to make sure our marriage stayed strong and as fun as it always was."

Although they are crossing their fingers that IVF will work again, the couple has plan B ready just in case. Giuliana adds, "We've gotten probably 40 women who have offered to be surrogates."

The pairing of E! News and Style star Giuliana Rancic and the Bachelor's and DWTS' Melissa Rycroft with sexy Victoria's Secret model Miranda Kerr seems a little strange at first...

But the ladies were at the Grove to promote the new Victoria's Secret Dream Angels Heavenly Enchanted, which makes perfect sense when you realize they're all living enchanted lives!

Normally, I pass up any fragrance ladies trying to spray me in the department stores, but with these three, I think I might have stopped and taken a whiff!
