Giuliana Rancic cried when she returned to work this week.

The 37-year-old E! News anchor - who welcomed her first son Edward Duke with her 41-year-old husband Bill Rancic via a gestational surrogate in August - returned from three-months maternity leave on Monday (12.11.12) and admits it was really hard.

She told Live From E!: ''It was hard to leave the little guy I'm not going to kid you. But you know pulling into the E! parking lot I swear to God it was like I'd never left. It came right back, it was like riding a bike.

''He's only three miles away. I'm fine. I'm going to do what most moms do. It is hard but hopefully I'm going to bring him in a couple of days of the week. He's so new. He's only 11 weeks old.''

Last month the 'Giuliana & Bill' reality TV star said she was so determined to succeed professionally that she forgot about her biological clock and was ''blindsided'' when they couldn't conceive a child.

She said: ''It was a big shock! I always say how I chased my career instead of chasing guys. And everybody was patting me on the back. No one ever told me, 'Oh, by the way, your eggs change when you reach a certain age.' I didn't think 35 was old.

''So when the doctor said, 'It's not as easy as you thought it would be,' it was a real blow. Because I felt so young. I mean, this is a girl who was running six miles a day, and eating healthy, so how can you tell me that I'm not healthy in that department?''
