ET goes inside "Ugly Betty" star Ana Ortiz's photoshoot!

The hot mama celebrated the impending birth of her first child by posing for celebrity pregnancy photographer Jennifer Loomis, and ET visited Ana and Jennifer on the set of their photo shoot.

"She's got a whole vision, she can see the picture as a whole it's great," Ana says about working with Jennifer. "I feel totally confident that she sees the whole picture and I don't have to worry about that. I can just let it go and let her do the work, and me just sort of have fun."

Ana and her rocker hubby Noah Lebenzon, are expecting baby No. 1 later this summer.

"I'm having a little girl which I'm really excited about," Ana says. "It's been a really nice pregnancy so I've been lucky. It's sort of nearing the end and I'm starting to feel a little bit ready, but I think that's part of the process."

Jennifer's book, Portraits of Pregnancy: The Birth of a Mother, will hit bookstores in June. Visit JenniferLoomis.com for more information.
