Sideshow | Hubby denies J.Lo is pregnant

Jennifer Lopez

is not pregnant, despite an avalanche of rumors and media reports to the contrary. (Seems J.Lo was spotted sporting a round tummy at New York Fashion Week.)

"Everyone calls about this every month with the hopes that they'll hit the mark - but no," J.Lo's hubby, Marc Anthony, said in a statement.

Comedy Central fake talk-show host

Stephen Colbert

, whose

The Colbert Report

has been hyped as the very salvation of political satire, has been accused by Air America radio host

Cenk Uygur

of joke pilfering.

In a video he posted on YouTube, Uygur, who jockeys the morning show The Young Turks, compares a joke he says he told Sept. 7 with one Colbert told on his show four days later.

And the joke? It makes the assertion that Republican presidential aspirants sound like Klingons (from Star Trek) when they bloviate about honor and valor and so forth.

A rep indicated Colbert - who, face it, is just a Jon Stewart wannabe - may address the issue on his show.

Could the fracas be a gag by Colbert, who often stages fake feuds a la Andy Kaufman? Sure.

"It's like a love story between two very unlikely people," said Jacobs' coauthor, William Stadiem. "Brett is a Rat Pack obsessive . . . I think he's channeling Frank sometimes."

Tucker, who will play Jacobs, spent the summer becoming buddies with the valet, who served Sinatra from '53 to '68.

"[The photos] are not real," De La Hoya's rep Debbie Caplan tells the N.Y. Daily News. She said the pics were doctored. "His head's too small and it doesn't even look like his body."

?

The N.Y. Daily News says Rose has gone surgery-happy and altered her face - that McGowan face the brothers so loved - way too much.

The 34-year-old actress admits only to having plastic surgery to fix an injured eye. But her rep says, "She was not pursuing this role."

Ricci will star opposite Emile Hirsch, who replaces another early casting choice, Zac Efron.

"Enough is enough." So said a full-page ad in USA Today Monday directed at comic

Kathy Griffin

. In its report, USA Today said the ad, which cost $90,440, was taken out by members of the Miracle Theater, a Christian theater troupe from Pigeon Forge, Tenn.

The thesps say they were shocked and appalled by Griffin's speech Sunday at the Emmy Awards. When she accepted her Emmy for My Life on the D-List, Griffin said "a lot of people come up here and thank Jesus for this award.

"I want you to know that no one had less to do with this award than Jesus." And, after making an off-color remark about Christ, she also said, "This award is my god now!"

"We at the Miracle Theater consider it an honor to stand for Jesus today," the ad said.

"We may never be household names. We may never be seen in Hollywood. Although others may choose to use their national platform to slander our God, we are honored as professional entertainers to stand for Christ."

Griffin has yet to respond.

So what's a sensible girl to do after a judge dubs her a "habitual" boozer and drug user and decrees she take random drug and booze tests?

Why, she oughta party down, dude!

Hours after getting a dressing down by Judge Scott Gordon in her custody case against Kevin Federline, Britney Spears was seen partying at various Hollywood hot spots. An anon source tells People that Brit and Avril Lavigne kept doing shots, while the New York Post can't confirm any alcohol was consumed. According to Gordon's orders, Brit must be sober at least 12 hours before going anywhere near her brood.
