"I'm head over heels in love." So kvells Christina Aguilera of month-old son Max Liron Bratman in the new issue of People, which appears to have won the rumored bidding war for the exclusive first pictures of the tyke (dad is her music exec hubby, Jordan Bratman).

Christina and Max's People cover

The glowing new mom (look closely beneath her unnecessary layers of makeup -- there's a definite glow) proudly poses with her adorably wrinkly offspring on the cover of the mag, gushing that "he's completely changed my life" and she's "in awe of this little miracle."

The poopy-pantsed wonder was delivered via scheduled C-section ("The hardest part was deciding on his birthday," she says), with his big debut set to the music of Miles Davis and captured on video by Bratman.

"We've played the [birth] video several times since, and all you can hear is me going, 'Oh my God!'" he says. "I was beaming the entire time."

According to Aguilera, "He's a good combination of both of us," and she boasts he's already exhibiting some telltale and seemingly non-gas-related facial expressions.

"He smiles a lot already, and he has the same little Elvis side smile that I do," she bubbles.

As for his musical tastes, they're apparently going to run the gamut.

"Yesterday we had Led Zeppelin blaring through the house," reveals the popster (by the by, their house is the same Mediterranean-style mansion the Osbournes occupied during their MTV series). "Most new moms play Beethoven, but we're playing Metallica, Bob Marley, the Stones."

Christina also gives the mag access to the nipper's nursery, which took four months to pull together and comes complete with a 24-hour baby nurse and a massive (and massively frightening) crescent moon that will likely give Max nightmares for many years to come (the grimacing, 11-foot monstrosity is from her last tour).

But such decorations are nothing compared with the supposed luxuries awaiting Jennifer Lopez's twins, who are due to arrive any second now.

According to PageSix.com, Mrs. Marc Anthony has designed the space in their Long Island home around an ocean theme, outfitting the room with cribs from France, furniture from England, glittery chandeliers and 18-karat gilded trim, because there's nothing like the extraneous use of precious metals to show how much you care.

Meanwhile, the Long Island hospital where Lopez is set to deliver her double bundles of joy (believed to be a boy and a girl) may be preparing for a worst-case scenario.

TMZ.com says staffers ran through a drill for a "Code Pink," the name given to the lockdown situation that happens in the event of a kidnapping.

While sources claim the training was specifically J.Lo-related, a hospital rep insists it was just a coincidence that it was held so close to her due date.
