Brad Pitt and Angelina Jolie must be growing weary of the constant tabloid predictions of their imminent demise.

Helpful sources close to the domestic-minded duo are speaking out in their defense, insisting to Us Weekly that all is well in their fabulous if poopie diaper-filled world, despite the doom-filled headlines, which this week include, "Angelina Looks Pregnant Again! Will another Child Solve Her Problems with Brad?" and the ever popular, "Jen Says: Brad Will Leave Angie!"

"He is at a great moment in his life," Kathleen Kennedy, the producer of Pitt's forthcoming flick "The Curious Case of Benjamin Button," gushes to the mag as she brushes off the strife chatter.

Jolie, with Maddox, Zahara and Shiloh in tow, often visits Pitt on the Beverly Hills set of "Ocean's Thirteen," reveals a mole, who says, "She comes almost every day."

Yet another insider adds that the comely clan usually holes up in Brad's trailer, where he earns points towards his inevitable Father of the Year prize by reading to his youngest and handling Pampers patrol.

Angelina, meanwhile, indulges in some couple time by turning the tykes over to a nanny and cheering Brad on as he emotes on camera.

"He constantly looks up at her ... and she gives him two thumbs up," relays the snitch.

"They are happier than ever," a Jolie confidante assures the magazine, "living life as a family, working, creating and helping the world."

And as for the aforementioned "Angelina Looks Pregnant Again!" headline, which comes courtesy of In Touch (seems the mag is convinced she's sporting a "telltale bump!"), Pitt's flack doesn't mince words.

"It's so stupid," the rep pooh-poohs to the New York Daily News. "That magazine is a joke."

Meanwhile, Justin Timberlake and Cameron Diaz have also been hit with talk of trouble in recent days, but they tried to put the rumors to rest Wednesday night by stepping out in New York looking lovey-dovey.

People reports the camera-dodging couple turned up holding hands at Timbaland's pre-MTV Video Music Awards bash at a Manhattan club, where the newly brunette actress was openly affectionate with her longtime love, who has been relentlessly promoting his album, "FutureSex/LoveSounds."

At one point, Diaz "put her arms around his neck and they hugged, then shared a private nuzzle in the middle of the jam-packed room," according to the mag, which says that when they made their getaway, she was "holding his hand from behind, leaning against him and snuggling into his neck."

The very public show of togetherness comes on the heels of a report in the New York Post that claimed the "SexyBack" crooner's "eyes were wandering" at a hotspot Monday night.

"He has not talked about her at all and comes off like a single guy," a mole maintained to the paper. "He is obsessed with his CD and not into having a girlfriend right now."

While that last part seems wide open to debate, Timberlake has been vocal about not wanting a wife right now. During a chat with Ellen DeGeneres this week, he laughed off questions about whether he was going to make things permanent with Diaz.

"Should I go ahead and get a bridesmaid's dress?" asked Ellen.

"Go ahead and reserve one," Justin quipped. "But you'll have to stay the same size for the next 15 years!"
