News anchor and Style Network star Giuliana Rancic is getting ready for her next challenge: juggling her career and motherhood.

Her son is due to make his debut just six weeks from now, via a gestational surrogate.
While the Rancics haven't decided whether to let their baby appear on their reality TV show "Giuliana & Bill," a few guest spots are not out of the question.

"We want our viewers to meet the baby and see the baby," she told Yahoo! Shine in an interview on Thursday. "We're not going to be those people who took the viewers on a journey and then that's it, cameras off."

But until he gets here, Rancic is focusing on fitness.

"I used to spend a lot of time on the treadmill, and I would be running for up to an hour at a time," she says. "It was incredibly boring, and caused a lot of joint pain, pain in the lower back, my neck would hurt."

She's switched in intervals on the treadmill a few times a week, and spends even more time on her new favorite workout: Zumba Toning. "It's the biggest blast ever!" she exclaims. "It doesn't feel like I'm working out at all… it feels almost like you're at a night club."

And she thinks it'll be perfect for parenthood, too, since she can switch over to the workout DVDs at home.

"Once the baby comes, I'm just not going to have time to go to the gym five days a week," she says. "I'm not going to want to. Those moments -- the couple of hours I have before work, I'm going to want to spend with the baby in the morning."

"I can put the baby in his little chair and he can watch me," she adds. "I'm sure the baby will be completely entertained! And if he starts crying, I can just push pause."

Rancic says that she's the most fit she's ever been in her life, and that's certainly saying something. The hardworking star was back on the set of E! News just two weeks after undergoing a double mastectomy and reconstruction. The operation reduced her breast cancer risk dramatically, but she was concerned that she wouldn't have fun in her fashion-forward job post-surgery.

"While I was recovering, I was thinking, 'I'm really going to be asking people what they're wearing?'," she told Glamour magazine in March. "I didn't know if I could find the joy in it again. But it didn't take long."

Instead, she zipped herself into a surgical bra -- worn under a designer dress -- and told her coworkers to stop walking on eggshells around her. "I walked in and these girls I'd seen every day--my assistant, my hair and makeup girls, who I'd have fun with and be crazy with--all had this sad look in their eyes," she told Glamour. "It was like… 'I'm the exact same person I was before. I'm still shallow, I still love clothes, I still want to talk fashion, I still want to gossip, so lay it on me.' They were like, 'Thank God'."

As much as she adores her job, though, she's planning to take time off once the baby arrives. "I'm taking quite a while off -- just shy of three months off," she told Yahoo! Shine. "I think that's really important, and I'm just so excited to bond with the baby."

In fact, the thing she looks forward to most about motherhood is "just the first day, meeting him," she says.

"I just can't wait to meet the baby, kiss the baby. It's been so long, just to see him and hold him. That's so thrilling. That's the first thing I'm looking forward to," she says. "Bill's going to be an incredible father. I can't wait to see Bill with the baby, to see that relationship blossom."
