Jessica Simpson called in to “On Air with Ryan Seacrest” Tuesday to talk about “Fashion Star” premiering tonight, her controversial nude cover for Elle Magazine, and her sex life while pregnant.

On Sex During Pregnancy:
“I am definitely feeling ‘intimate.’ I’m kind of unstoppable at the moment! Like the big ‘O’ is like the biggest ‘O’ ever.” How is fiancé Eric Johnson responding to it all? ”He’s always ready. He’s always ready!”

On Her Nude Elle Magazine Cover:
“They didn’t even ask me to do that. I just booked the cover for Elle and it was my idea. It kind of just seemed like a natural thing for me to do….I just take such pride in being a mom and I just love my body more than ever right now.” The fashionista wasn’t worried saying, “It was a closed set, so I felt really comfortable. It was just Eric, my fiancé, and a couple of my friends.”

What Is Jessica Naming Her Baby Girl?
Fans have spotted Jessica with the letter ‘M’ around her neck, but she’s staying tight lipped regarding it’s meaning saying, “Yes, everybody is asking about the name, but that will come whenever the baby is delivered.” But does that mean the first consonant is actually an ‘M?’ “It is definitely a new name that will be in our lives,” she coyly responds.

On Tonight’s ‘Fashion Star’ Premiere:
“I feel like we’ve had the opportunity to kind of style America. Watching the show, its kind of like a magazine come to life, in a lot of ways. It’s like looking through a fun fashion spread.”
