Ryan Gosling and Rachel McAdams haven't exactly been shy about expressing their mutual admiration, but are they ready to share their warm and fuzzy feelings while swapping rings in front of their nearest and dearest? The wedding whispers that have long dogged the swoon-inducing "Notebook" sweethearts are growing louder, with a McAdams mole telling Us Weekly, "They're madly in love and plan on getting married this year." The snitch adds that Ryan, 26, and Rachel, 28, are determined to keep things hush-hush, "so they agreed to get engaged and married on the same day -- and won't allow their families to talk about it." Not so, insists McAdams' rep, who tells the mag that mumblings of a surreptitious ceremony are "completely false."

Meanwhile, the tabloids are doing their darndest to get Leonardo DiCaprio to settle down. Just weeks after his camp refuted reports that he and his Sports Illustrated model girlfriend Bar Refaeli, 21, were about to tie the knot comes word from the London Daily Mirror that the lovebirds of little more than a year are "delighted" to be awaiting a genetically gifted delivery from the stork. And even though the bun-in-the-oven rumors appear to be based on little more than Bar wearing a billowy blouse and sipping water during a recent night out in Las Vegas, that hasn't stopped the paper from detailing how the A-list actor, 32, is already soliciting parenting advice from pal Tobey Maguire, who became a father late last year. "He dotes on Tobey's little girl, Ruby, and has been asking him all about what it's like being a dad," a mole tells the tab. But it looks like Leo may just be making polite small talk with his dirty-diaper-surrounded buddy. A source close to DiCaprio tells MSN.com that the baby burblings are a bunch of hooey.

Matthew McConaughey's tireless campaign of shirt-doffing and pecs-flexing has finally paid off -- word is he's ensnared a nubile beauty.

David Arquette isn't fazed by rumors that his almost 8-year-old marriage to Courteney Cox has hit a rough patch. "They'll say what they're gonna say and you just say 'No, that's not true,'" he told Los Angeles radio station Star 98.7 this week. "It's all sort of fun anyway." The Cox-Arquettes braved the tabloids' inevitable dissection of their body language when they posed together Wednesday night at the cemetery-set premiere of David's new horror movie "The Tripper." "At every turn, it's my job to be loving and honest to her," Arquette tells People of his well-preserved wife. "If there's one thing about our relationship, there are no surprises." Huh, is it just us, or does "no surprises" sound more like a negative? Must just be us.

In recent months, the busy lips of Bruce Willis have puckered up to both Drew Barrymore and Courtney Love, but have they found a new smooching partner? The New York Post says the chrome-domed star was spied kissing his "Perfect Stranger" co-star Tamara Feldman at the flick's New York premiere Tuesday night. Meanwhile, the model Willis is rumored to have unsuccessfully courted says she's enjoying flying solo.

Katie Couric could probably use a strong shoulder to cry on after being eviscerated in the new issue of the National Enquirer, and the New York Post says she's found exactly that in a triathlete nearly 20 years her junior.

Couric was introduced to the jock through mutual pals and is said to be "very happy," according to the paper.
