Has Christina Aguilera proved that even seemingly dangerous amounts of self-tanner won't affect one's ability to procreate? Not so much, according to the New York Daily News, which says the perpetually bronzed pop princess, 26, is denying that she popped by Los Angeles baby boutique Bellini on Saturday and dropped $3,000 on baby gear, along with some major news.

"She came in with her husband [Jordan Bratman], and he sat in one of the big chairs and let her do her shopping," a chatty (and seemingly promotion-savvy) staffer alleges to the paper. "They said they don't know what they're having."

The clerk adds that the naked Sunday enthusiasts "seemed really excited. She was talking to [another customer] and she said she took a home pregnancy test and that it was positive. She kept saying they'd have to come back when they knew the sex of the baby."

But Christina, who kicked off the U.S. leg of her Back to Basics Tour to strong reviews Tuesday night, adamantly pooh-poohs the pitter-patter of little feet prattle, with her rep insisting to the paper, "She said it is not true and she wasn't in Bellini."

Not content with one denial, the flack reiterates Christina's bundle-of-joylessness to Us Weekly, scoffing, "It's all made up ... She was not at Bellini. She was on a plane to Las Vegas for the NBA [All-Star] appearance.

Also working against the pregnancy rumblings: Aguilera, who showed off her flat-as-a-steamrollered-pancake stomach in various ultra-clingy Cavalli costumes during her concert this week, spent Valentine's Day at Disneyland screaming in delight as she enjoyed the Matterhorn with Bratman, a ride not recommended for expectant moms.

(If you're curious, the items she says she didn't purchase include several onesies, a few super-cozy baby blankets, a $350 polka-dot diaper bag and a high-end stroller, says In Touch.)

The Cheeto-hued chanteuse has made no secret of her family plans, admitting to Elle UK last March that she "always knew I wanted to be a young mother."

But four months later, she told a British interviewer, "In five years time I'd probably like to start thinking about a child, and probably writing about that experience in my life on my next record."

In other baby news, the he-said, she-said battle between squeaky-clean New England Patriots star Tom Brady and his pregnant ex, Bridget Moynahan, rages on, with neither side apparently yet grasping that their offspring will one day read about his or her contentious beginnings.

"He's disappointed this is how she's decided to play it," a Brady buddy whines to Us. "She announced it to make him look like a jerk."

The friend concedes that the quarterback, who's spent the last few days snuggling up to Gisele Bundchen in Paris, has known about the impending stork visit "for a while" (the actress went public this week), but says neither was aware of the bun in the oven when they called it quits in November after three years of togetherness.

As for Bundchen, she didn't appear to be letting the ankle-biter news ruin their romantic sojourn in the City of Light.

"Whenever he started to look stern," says the mole, "Gisele would give him a kiss and say, 'Stay cool.'"

The official word from Brady's camp is that he and his family are "excited about the pregnancy."

Meanwhile, the belly watch continues for Naomi Watts, who remains mum on reports that she and boyfriend Liev Schreiber will soon join the poopie pants brigade.

A spy tells Us that when the unassuming squeezes dined out with friends last weekend at New York eatery Pastis, "Naomi was visibly pregnant. Liev was smiling and looking at her stomach. They were cute."

And finally, two names we hoped never to hear again are back in the news. Trista and Ryan Sutter, who met on "The Bachelorette" in 2002 and pledged their eternal love in front of 26 million of their closest friends during a TV special a year later, are awaiting the arrival of their first child, reports People.

"We are so happy after two years of trying," says Trista, who is three months gone. "I've had horrendous morning sickness, but everyone says that is a sign of a healthy pregnancy."

No word on whether they plan to share the delivery and the tot's formative years with the world.
