Ethan Hawke has beat newly engaged ex-wife Uma Thurman to the altar. An insider tells People he said "I do" with about-to-pop fiancée Ryan Shawhughes three weeks ago, not long after they were spotted taking out a marriage license in New York. The actor's rep confirmed the nuptials to The Associated Press but was light on details other than that the ceremony was held last month in Manhattan. Meanwhile, the mole reveals to People that the couple is expecting a baby girl, who will be Hawke's third child (he's already dad to daughter Maya, 10, and son Levon, 6, with Thurman, whom he split with in 2004 after seven years of marriage). Shawhughes is new to the mommy thing, but she won't have a steep learning curve. The couple met when Ethan was still married to Uma and Ryan was working as their nanny. "She had nothing to do with the divorce and they started seeing each other after she was no longer the children's nanny," a source assured the New York Daily News in December, adding for good measure, "They are incredibly in love."

Kirsten, Josh and Susan at a New York screening of "August" on July 9

Persistence apparently pays off when you're attempting to woo Kirsten Dunst. The New York Post says the actress was spied playing tonsil hockey at New York's Beatrice Inn with the club's DJ, Matt Creed, a longtime friend whom she was linked with last month. "She kept resisting his PDA advances," an eyewitness tells the paper, "but finally gave in and made out with him." The next night, Dunst's attentions were supposedly on her "Virgin Suicides" co-star -- and onetime smooching partner -- Josh Hartnett. A Defamer operative spotted her "laughing and chatting" with the facial hair-challenged actor, a tête-à-tête that took place six months after they reportedly swapped spit with at the Sundance Film Festival. While there wasn't any lip-to-lip contact, "their faces were so close, they might as well have been Eskimo-kissing," picture-paints the eyewitness. Perhaps the pair was just making plans for Wednesday night, when they posed for pictures with Susan Sarandon at a screening of Hartnett's forthcoming drama, "August."

Is history repeating itself for Cher? The National Enquirer claims the iconic entertainer, 62, is planning to tie the knot in Las Vegas with a 38-year-old mountain-climbing adventurer named Tim Medvetz. This would make the second Sin City vow-swap for Cher, who wed Gregg Allman there in 1975, three days after her divorce from Sonny Bono was finalized. Their wedded bliss lasted until she filed for divorce nine days later, although they eventually reconciled and stuck together for another three years. So, will Cher say "I Got You, Babe" for the third time? Not according to her spokeswoman, who tells People the story is "crazy," adding that the well-preserved legend's assistant "was laughing hysterically" when she called to ask about the nuptial whispers.

John appears to reach for Jen's hand as they brave a paparazzi barrage at the wrap party for "Marley & Me" in Miami.

In this week's edition of dubious Jennifer Aniston-John Mayer news comes a nugget from New York Post, which claims the actress found a cache of love letters penned by former flame Jessica Simpson in his guitar case. "Jennifer was more hurt than angry at the discovery," a snitch maintains to the paper. "The letters surprisingly were very touching and well written." Not to worry, though, because Aniston was said to be "fine" after the crooner "smoothed things over." A few questions: Why would Aniston poke around in Mayer's guitar case? Also, why would she read anything she found in said case? And why would he be hauling around the missives to begin with? Plus, did Jessica send these love letters by text message? Because we have a hard time imagining her sitting down with pen and paper. For the record, Jen's rep tells the paper the story is "completely fabricated." Mayer, meanwhile, is still chugging along on his North American tour, although Aniston has reportedly returned to Los Angeles after cheering him on backstage at several concert dates. During a promotional stop this week at New York's Z100 radio station, John was asked whether he'd ever "hooked up" with an audience member. "Do you respect my honesty?" he responded, before fessing up, "Yes, I have. But that was before camera phones were around."

In related Mayer news, OK! claims Cameron Diaz has been in touch with her former dirty-dancing partner to tell him how swimmingly things are going with British model Paul Sculfor, whom you'll recall had a brief interlude with Aniston last summer. The mag says the actress and Sculfor were seen last week in L.A. getting in some culture and cuddling at the Getty Museum. "They were giggling and kissing the whole time," says a bystander.

Jessica Biel isn't holding her breath for a bended-knee proposal from Justin Timberlake, who in recent months has laughed off engagement rumblings during chats with Ellen DeGeneres and Jay Leno. "You know, the actual idea of signing those papers and doing all this stuff about it, I've never been someone who's like, 'I have to, have to, have to have it," the hard-bodied starlet, who has reportedly moved into the crooner's Los Angeles pad, tells the August issue of Harper's Bazaar. "But the idea of being with somebody I care about, who's my soul mate, that sounds groovy."

Did Lindsay Lohan unwrap something bright and shiny from Samantha Ronson for her 22nd birthday? Just days after the bosom buddies were snapped checking out the sparkly wares at Cartier in Beverly Hills, the London Daily Mirror says the lately line-toeing actress received a $22,000 diamond ring from the DJ. "It's not an engagement ring -- simply a token of her commitment," a source tells the paper. "Lindsay is thrilled and she and Sam are very content."

Brian Austin Green is marking his territory. The onetime "Beverly Hills, 90210" heartthrob, 34, denies he and sexiest list-topping fiancée Megan Fox, 22, are kaput. "We're solid," he insists to TV Guide. "We've lived together for three years. We have tattoos of each other's names." We hate to break it to Brian, but a permanent ink stain does not guarantee a happily ever after, as evidenced by the likes of Angelina Jolie ("Billy Bob"), Johnny Depp ("Winona Forever"), Denise Richards ("Charlie") and Roseanne ("Property of Tom Arnold"). Green does allow that they spend "more time away from each other right now than we'd like," but says the "biggest problem" in their relationship "is rescuing pets from pet stores. We have a potbellied pig, we have dogs, two cats, two birds, a squirrel."
