For the second time this year, Christina Aguilera's womb is under intense scrutiny. Seems the pocketsize, peroxide-locked chanteuse has touched off a new round of bundle-of-joy jabbering after she was spotted last Thursday at a New York doctor's office.

TMZ.com reports Christina, 26, and her music-exec hubby Jordan Bratman, 30, paid a visit to Manhattan's Maternal Fetal Medicine Associates, a practice specializing in "high-risk obstetrics and state-of-the-art ultrasound."

A pack of paparazzi was on hand to document the outing, which came just days after the low-key, naked Sunday-enjoying couple was snapped exiting Cedars-Sinai hospital in Los Angeles.

Also sending stork speculation into overdrive: Aguilera has lately taken to covering up her typically on-display mid-section with various accessories, including a scarf, notebook, and a sweater.

Meanwhile, Britain's News of the World claims she "looked to be sporting a small bump" while doing some retail therapy in NYC, with a "pal" telling the tab, "Christina and Jordan adore each other and have tried for a baby for a while to complete the family."

So, what's the official word on this latest round of procreation rumbling?

"I cannot confirm [the reports]," the singer's spokeswoman sidesteps to MSN Entertainment.

You'll recall that back in February, Christina's rep pooh-poohed the pregnancy rumors, which began after she purportedly plunked down $3,000 at a swanky L.A. baby boutique.

"She was talking to [another customer] and she said she took a home pregnancy test and that it was positive," a source tattled to the New York Daily News at the time. "She kept saying they'd have to come back when they knew the sex of the baby."

Not so, said Aguilera, who maintained she was en route to a performance when the supposed shopping spree took place.

The self-tanner- and face-paint-addicted pop princess has made no secret of her desire to have a family, but she's repeatedly insisted she's in no rush to discover the wonders of the Diaper Genie (feel free to insert your own "Genie in a Bottle" pun here).

"I do have a schedule for myself and goals I want to achieve, but it's definitely on the list of things to do in the next few years," Xtina told People in March. "We'll have fun trying in the meantime!"
