Talk about too much information.

Not content with stripping off and posing naked, heavily pregnant Jessica Simpson has been chatting about her sex life.

The American singer, 31, told Ryan Seacrest on his KIIS FM radio show in the States that she can't get enough nookie, despite being almost ready to pop with her first child with Eric Johnson.

"I am definitely feeling 'intimate," 'fessed Jess. "I'm kind of unstoppable at the moment. Like, the big 'O' is like the biggest 'O' ever!"

She also spilled the beans on her naked magazine cover for ELLE, admitting Doing a Demi was all her idea.

"They didn't even ask me to do that. It was my idea. It kind of just seemed a natural thing for me to do," she said.

"I'm like 170 pounds and I wanted to pose nude. I try to be like 110 pounds. It's funny to be at your heaviest and feel the most confident. I just take such pride in being a mom! I just love my body more than ever now."

Thanks for the updates, as ever, Jess...
