Jennifer Aniston and John Mayer don't seem too worried about overindulging on together-time. On Wednesday, the carefully coiffed couple moved their well-documented schmoopiness from Miami to New York, where they hit the paparazzi-surrounded Waverly Inn for a low-key dinner with pals. "Jennifer was just smiling and looking on, clearly in love with him and acting like he was the smartest guy on Earth," a picture-painting, conclusion-leaping eyewitness relays to Us. "She rubbed his back several times and they had their hands touching under the table. It was really cute!" People reports the joke-cracking singer-songwriter, 30, who was spied sneaking a backstage kiss from the tanned and toned actress, 39, during a performance in Orlando Tuesday night, kept her laughing during their meal. (For those wondering -- and you know who you are -- Us says they split a $55 plate of truffle mac and cheese.) Jen and John foiled shutterbugs trying to get a shot of them together by exiting the eatery separately. They then headed over to Hudson Bar and Books, where they were "kissing, hugging and posing for photos together," reports People. And the definitive sign that they're smitten? Mayer got funky and did a "goofy little dance" for Aniston, who refrained from covering her face in embarrassment. They were later seen entering -- separately, of course -- Jen's New York hotel.

Mariah and Nick: two months and counting ...

For Mariah Carey and Nick Cannon, domestic bliss is apparently even more blissful when there are cameras around to capture every perfect moment. Not only did the so-called "soul mates" pony up their wedding pics to People magazine, but they're also offering snaps of their post-wedding bash at Six Flags Magic Mountain on Tuesday night. If these pictures are any indication, nothing says true love forever more than staring directly at the camera, diamond rings prominently flashing, while saying "whee!" on a roller coaster. Anyhoo, someone who's supposedly not feeling the fun these days is Mariah's ex, music producer Mark Sudack. Us Weekly reports that even though he and the high-maintenance chart-topper quietly broke up in early 2008 after more than three years of under-the-radar coupledom, Sudack feels "shattered" over her impulsive "I dos." "Everyone is scared to call him because no one knows what to say," a "pal" blabs to the mag. "He never thought she would go off and marry someone else. He's heartbroken and shocked."

Rihanna recently admitted that she and Chris Brown are "very close now," and it appears the camera-shy couple is out to prove just how close that is. According to People, the musical squeezes got touchy-feely Wednesday night at a Kanye West concert in New York, with the chanteuse, 20, puckering up for a "big kiss" with the crooner. It's the latest round of PDA for the affectionate pair, who have been snapped in several snuggly poses over the last few months, including last week at a Miami KFC, where Rihanna was captured leaning in for a smooch and wrapping her arms around Brown.

Kate Bosworth doesn't have a parasite.

Kate Bosworth is placing the blame for her once painfully bony figure on her breakup with Orlando Bloom. In an interview with Harper's Bazaar (via Australia's Daily Telegraph), she says the implosion of their romance after four capricious years together left her so stressed out she had no appetite, resulting in her cricketlike form and prompting headlines questioning her health. "It was my first very difficult breakup with someone I loved deeply and no matter how much I ate, it didn't matter," says the still twiggy actress, who began dating strapping model James Rousseau not long after she and Bloom parted ways. "I hold all my emotions in the pit of my stomach, so it became difficult to eat. I remember going to a nutritionist and asking, 'Do I have a parasite?"'

Kirsten Dunst has been handed her walking papers, but not, it seems, by Ryan Gosling, with whom she's recently been seen spending time. WWD reports the snaggletoothed actress is being replaced as the face of Miu Miu by gap-toothed Vanessa Paradis, the fashion-forward longtime love of Johnny Depp. On the plus side, FoxNews.com claims "things are getting serious" between Dunst and Gosling, who are co-starring in the drama "All Good Things." "She is at a point where she wants to settle down," maintains an insider. "Ryan is good for her."
