It's shaping up to be a very happy new year for Christina Aguilera. According to Page Six, which apparently has the makeup-slathered singer's obstetrician on speed-dial, she's scheduled to undergo a C-section on Jan. 10. Of course, there's always a chance the tyke, rumored to be a boy, could debut sooner, but the parents-to-be appear to be well-prepared for the arrival. The paper says Christina and hubby Jordan Bratman, who stepped out together Tuesday night in Los Angeles to celebrate the belter's 27th birthday, have narrowed down their list of names, and they are said to be partial to the refreshingly playground-proof monikers Max and Jackson Jake.

Lily Allen at the British Fashion Awards in London on Nov. 27

Meanwhile, Lily Allen has wasted no time in turning her fledgling relationship into a lifetime commitment. A rep for the blunt, kvetch-prone British chanteuse, 22, confirms she's expecting an ankle-biter with rocker-beau Ed Simons, 37, of the Chemical Brothers, whom she's been dating for three whole months (yes, three). "The health of Lily and her child is their paramount concern," explained her mouthpiece (via Us). "As the pregnancy is at such an early stage, the couple will be making no further comment, but they are obviously thrilled by the news." Allen is already catching flack over a photo from a couple weeks back that showed her puffing on a cigarette, although her rep insists to the London Daily Mail that she wasn't aware at the time she was in the family way. "Lily is thrilled to be pregnant and can't wait to become a mum," a source tells the London Sun, which broke the story. "She's a real family person. Ed's very happy. He is really looking after her."

It seemed inevitable that Jennifer Love Hewitt, who recently made the cover of People defending her normal-sized bod ("Stop Calling Me Fat!"), would be hit with baby rumblings (sadly, pregnancy is one of the few times an actress is allowed to embrace her curves without criticism). The New York Daily News reports a "little bird close" to the no-respect-getting "Ghost Whisperer" actress claims she's expecting a bundle of joy with newly minted fiancé Ross McCall. However, her rep is quick to shoot down the stork whispers, pooh-poohing to the paper that they're "100 percent false. She is not pregnant."

Is there a good reason why Fantasia Barrino has missed so many performances of the Broadway hit "The Color Purple"? The New York Post, citing chatter in the blogosphere, speculates the "American Idol" winner could be pregnant. But a rep for Barrino, 23, who has a 6-year-old daughter, denies the baby talk to Us, insisting, "Fantasia is not pregnant and the Internet rumors are entirely untrue."

It's nice to know those circulation-slowing tights Chris O'Donnell once donned to play Batman's little buddy Robin didn't adversely affect his procreation plans. People reports the actor's wife, Caroline, just gave birth to their fifth tyke. Maeve Frances O'Donnell arrived on Dec. 10 in Los Angeles, joining sister Lily, 8, and brothers Chip, 7, Charlie, 4, and Finley, 1. "Everyone's happy," O'Donnell's rep tells the mag. "Mother and baby are doing great."
