Brad Pitt and Angelina Jolie couldn't keep their hands -- or lips -- off each at the weekend premiere of "The Assassination of Jesse James by the Coward Robert Ford" in Toronto, but it turns out their cuddle-buddies weren't just for the cameras. The National Post says the tabloid-topping, impossibly pretty pair continued to paw at one another at a star-crammed shindig on the roof of their hotel, where their heat was "perfectly palpable." Angelina was spotted leaning against a wall as she "cradled" Brad from behind, giving him a shoulder rub and "playfully" unbuttoning his shirt (no word on whether the unfastening was low enough to reveal his new stomach tattoo, which features his amour's birthdate). By Monday, the Jolie-Pitts were back to their domestic routine in New York, where snappers trailed them as they dropped off 6-year-old Maddox at his exclusive private school and treated a likely thrilled Pax, 3, and Zahara, 2, to a trip to FAO Schwarz.

Meanwhile, on the other end of the touchy feely spectrum in Toronto were Reese Witherspoon and Jake Gyllenhaal, who kept their distance while stumping for their forthcoming drama, "Rendition." But it turns out there were a few sightings of the rumored squeezes getting up close and personal over the weekend. Time magazine reports they "danced briefly but divinely" at a swanky soiree, while the National Post says Witherspoon swung by to pick up Gyllenhaal after he finished chowing down at an Italian restaurant.

Ashlee Simpson and Pete Wentz apparently have very different ideas about the meaning of PDA. The New York Daily News says the visage-overhauling starlet and the guy-liner-loving Fall Out Boy bassist were all over each other at a Rock & Republic bash last week in New York, with Ash's skirt "riding up her hips while she wriggled in his lap." But Wentz wasn't paying all that much attention to Simpson's overexposure during their public display of affection. In a move that would seem to indicate he's growing a bit bored with spit-shining Ashlee's tonsils, Pete was reportedly checking messages on his PDA behind her head as they tangled tongues. But that didn't stop him from gushing about Simpson at the VMAs, telling People, "The truth is, it's crazy to be able to kiss your best friend. It's just a really awesome thing."

More than 40 years after his heyday as the cute Beatle, Paul McCartney still has a way with the ladies. After recently chatting up Christie Brinkley and reportedly cozying up to Renee Zellweger, the not-quite-divorced pop icon, 65, enjoyed an "intimate" tête-à-tête with Elle Macpherson, 43, during the GQ Men of the Year awards show in London last week, reports the Daily Mail. The McSnuggly pair was snapped laughing, whispering and being generally tactile during the ceremony, where Elton John gave McCartney props as "the greatest living songwriter."

Meanwhile, is Kylie Minogue also immune to Bloom's ineffable charms? According to the London Sun, the actor "made a beeline" for the pop queen at a recent benefit bash, only to have her beat a hasty retreat to a nightclub. Orlando was supposedly left red-faced at her exit, with a spy telling the paper, "He tried to laugh it off but you could tell he was gutted."

Has Jeremy Piven succeeded where Bruce Willis failed? The "Entourage" star was spied getting oodles of attention from Petra Nemcova at a Prada soiree in New York last week. The tsunami-surviving model, who reportedly warded off Willis' wooing attempts last year, "cupped Piven's face in her hand and cooed like a baby," reports the New York Daily News. According to New York magazine, Nemcova also "held his hand and dragged him all over the party, and when someone asked her what she was doing next, she turned to Piven and said, 'What are we doing next?'" Perhaps Petra was just showing appreciation for the actor's support of her Happy Hearts charity bash, which the New York Post says he's set to host.

The former flame of Kirsten Dunst traces the demise of their romance to differing views on two very important issues: cleanliness and cuisine. "We were leading different lifestyles. It's over," Johnny Borrell is quoted as telling the London Daily Mirror. "She believes in equality, that a bloke should chip in with the housework. Fair enough, but I'm messy ..." The Razorlight front man, who began dating the actress in March, also reveals that his love of cancer sticks and meat on a stick were sticking points. "She couldn't stand the smell of stale [cigarettes], beer and kebabs in her nice living room," he says. "Can't say I blame her, really." Borrell adds that their opposing sleep patterns also caused problems: "I'm very much a night owl, and she's up with the lark." But the shaggy haired rocker isn't harboring any ill will over the bust-up, saying of his ex, "She's a really cool girl and she loves London and Britain. It was just one of those things."

Looks like Lance Armstrong is pedaling solo these days. The Tour de France champ has called it quits with designer Tory Burch after about 9 months of togetherness, reports Us Weekly. "It was a distance thing," says an Armstrong insider. Not so, maintains a Burch pal, who tells the mag, "Tory would have moved to Texas for him if he popped the question. But he didn't want to commit." Meanwhile, does Armstrong already have someone in mind to fill the empty seat on his tandem bike? In Touch claims Armstrong recently bumped into Jennifer Aniston at a Los Angeles eatery and ended up trading digits with her. But the actress' rep denies there was any information exchanged, insisting they chatted for only a few minutes. One reason to believe the mouthpiece: Jen is known for being a loyal friend, which means she'd probably shy away from dating the guy who was once engaged to her pal Sheryl Crow.
