We can handle the relentless partying. And the beau-hopping. And even the ladyparts flashing. But what we can't handle are the whispers that Britney Spears might have yet another bun in her oft-occupied oven.

(We know, we know ... and we're right there with you.)

But don't put the stork on your hit list just yet. The terrifying rumor has thankfully been denounced faster than Kevin Federline at a rappers' convention.

"Britney is not pregnant," declares her raise-needing manager Larry Rudolph to Us Weekly, labeling as "absurd" reports that 16-month-old Sean Preston and 4-month-old Jayden James (you can do the math on Spears' rapid-fire procreating) would soon have to share their already precious mommy time.

The Big Debate: Britney vs. K-Fed

Rudolph suspects the baby babbling began last week after the spiraling pop starlet was accused of vomiting all over her brave new squeeze, Isaac Cohen, who was quick to put the kibosh on the cookie-tossing claims.

According to Cohen, the icky, sticky chunks paparazzi caught clinging to his hands and shirt while he and Brit were in his car (warning: skip this next part if you're eating or ever want to crave the creamy goodness of Jif ever again) was merely some spilled peanut butter.

"It's ridiculous. Because someone didn't lick peanut butter off his finger, she's pregnant," Rudolph tells Us of the morning sickness mumblings. "That's how ridiculous it is."

Speculation over the contents of Spears' uterus tops the cover of this week's In Touch, which also points out her supposed lack of imbibing while whooping it up in Sin City on Jan. 14, her recent packing on of a few pounds and her sleepiness on New Year's Eve.

"I've seen her during the last two pregnancies and she has the same look now," a "close pal" posits to the mag. "She's heavier, but that's not it. It's the sparkle in her eye. She always gets that sparkle when she's pregnant, like she's relaxed and happy."

Of course, that "sparkle" wasn't always on display when she was carrying the still-unseen Jayden, as her mascara-streaked, false eyelash-flailing sit-down with Matt Lauer last summer proved.

As for the apparent alcohol nixing, that's news to People, which reports she was quaffing Dom Perignon while club-hopping into the wee hours during her weekend getaway to Las Vegas.

Spears enjoyed the snooze-inducing town with the peanut butter-craving Cohen, who is learning there are a few benefits to dating a dysfunctional if deep-pocketed mommy of two.

People says the lovebirds, both 25, holed up in a $40,000-a-night, two-story suite at The Palms hotel, complete with a rotating bed (perfect for the non-chunk-blowing Brit), glass elevator, Jacuzzi and full bar.

"They seem very happy together," a mole tells the mag.
