I guess Britney Spears set the baby-belly-baring bar last year, so naturally Christina Aguilera couldn’t help but respond in kind, smack on the front of the upcoming January issue of Marie Claire.

Which one is the pop-tartiest? Dead heat, I say. As always, it’s the children who ultimately suffer.

Speaking of which, I have an inkling of Baby Aguilera’s name-to-be:

“We were planning on starting to try after the tour. And so, I had gone off the Pill to prepare my body, because I didn’t know how much time it would take. You’ve heard it takes some time — except with Power Egg and Super Sperm here,” she says. “… I’m like, `Oh my god, can you believe it just happened?’”

Power Egg and Super Sperm. I like it — sounds like some kind of superhero tandem. And if you make an acronym out of it, you get Pess. Which is no goofier a celebr-baby name than Apple, Shiloh, Suri, etc.
