Giuliana Rancic has explained that she felt “at ease” when she witnessed the birth of her son.

The E! News anchor and her husband Bill Rancic welcomed their son, Edward Duke, into the world in August via a gestational surrogate.

Giuliana admitted that although she was expecting to be nervous in the delivery room, she knew as soon as she saw the newborn she would be able to look after him.

In an upcoming episode of Giuliana and Bill, the 37-year-old TV presenter said: ''It feels good. I'm not nervous at all. I feel like I can take care of him. I expected to be more nervous and more flustered, like I had no idea what to do. But I feel totally at ease. I just feel like I know what he needs.''

Bill also spoke about of his joy about his son saying: ''This kid is like, super chill, man.''

The couple had first undergone several failed attempts of IVF, followed by Giuliana's subsequent diagnosis with breast cancer.
