Is Christina Aguilera with Bun?

Recently, Christina Aguilera and her husband, Jordan Bratman, were both seen at a doctor’s office in New York, rekindling pregnancy rumors that had been fired up earlier this year after the petite pop star was spotted spending $3,000 at a fancy baby store in Los Angeles. 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.”

Only days earlier, the young couple was spotted in Los Angeles leaving the Cedars-Sinai hospital. And there’s also talk of a baby bump, which X-tina seems to have been very cleverly concealing when out in public lately, using such various props as a notebook, sweater and scarf.

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.”

Aguilera’s rep neither denies nor confirms any reports that the tiny bottle-blonde is with child, but we can all sit here and enjoy a hot cup of nice speculation, nonetheless. I just wonder what that unavoidable conversation is going to be like when the child eventually will have to ask his or her mommy, “Why aren’t I orange like you? Am I adopted?”
