Hook Ups

Mayer will be performing in Jacksonville on the 25th, and Jessica seems to be going along for the ride. Just a few months ago, Jessica weathered a media backlash for her then publicist's mistake of going public with the Mayer romance and then denying it. Now Jess is on board and on the bus.

Sources close to both Moore and AM (real name: Adam Goldstein) confirm to TMZ that the pair is "definitely" a couple. We're also told that the couple are "happy" and "the cutest the thing you've ever seen." Awww.

Moore, whose last paramour was actor Zach Braff, and Goldstein, who famously dated Nicole Richie, were spotted canoodling in a coffee shop on Main Street in Park City, Utah. According to a TMZ spy, the pair made their way outside and Goldstein lit a smoke -- but Mandy wanted a smooch even before Adam could finish his cancer stick, and pulled it out of his mouth to plant a wet one on her new boy's lips.

Though perhaps not putting on quite as good a show as Tara Reid, Mandy and DJ AM have demonstrated that it's not all snow, cold and Mormons in Utah.

Simpson and quirky crooner John Mayer were spotted hand-in-hand in South Beach after having dinner at the Shore Club's Nobu, making their first public appearance together since New Year's Eve. Jessica also put her girls on display for the occasion, beaming her cleavage to her oh-so-lucky date.

The not-yet-confirmed couple was spotted coming out of Beverly Hills Pimps & Hos on Sunday, where Harry, owner of the Pink Taco restaurant chain, covered his face with a sweatshirt in an attempt to block photogs from getting a shot of him with Stewart.

The relationship is over, but the drama has just begun -- and it looks like Cameron Diaz is hooking up to make Justin Timberlake jealous.

According to TMZ spies, Cameron is currently camped out on the North Shore of Oahu, Hawaii with super surf stud and current ASP World Tour champ Kelly Slater.

We're told the couple shared a romantic oceanfront dinner at Haleiwa Joe's restaurant before heading back to Slater's place. Indeed, we're told Cameron is staying with Slater. The two have been friends for years; Slater even appeared on Cameron's MTV show "Trippin" in 2005.

Other TMZ spies tell us that during the Golden Globes, Cameron kept coming up to Justin's table, trying to engage him in conversation.

Each time she left, a frustrated Justin made it clear he just wanted a clean break.

When you're a funny, charming and handsome star like Zach Braff, there aren't many women out of your reach, right? Not so much.

A TMZ spy spotted Zach at a party in Hollywood where the "Scrubs" star was trying to sweet-talk one of the female caterers.

He pulled every card he had up his sleeve -- but to no avail. After telling the server how beautiful she was and informing her that he would have her added to the guest list at Hyde, she still kindly refused. Although Braff didn't show any signs of a bruised ego, it had to hurt.

The reconciled BFFs gorged on junk food during one of Justin's slower numbers at L.A.'s Staples center. Paris, seen here leaving her house for the concert, had her hands full with hot dogs, a pretzel and a Red Bull, while Nicole tried to fill out her petite frame with a huge plate of nachos and a soda almost as big as she is. The bingeing buddies, with a tween friend at their side, then maneuvered their way (on the correct side of the road) to their seats, just in time to catch JT performing a version of Nicole's father Lionel's hit song "Easy." Whatever could JT have meant by that?

Paris' sister Nicky was also there with her new boyfriend, Mary-Kate Olsen's ex, David Katzenberg. To make sure their date night didn't get too hot and heavy, the young lovers were chaperoned by David's dad, media mogul Jeffrey Katzenberg.

The sexy duo were spotted at some of L.A. and Vegas' hottest gay bars and clubs. Some think that the reason for the gay venue visits is because that's where Isaac Cohen likes to go. The truth is: it isn't so.

TMZ's inside sources say that the rumors are simply not true. Not only is this pairing not an act, but Britney and Isaac are actually holding back while in public. Our spy said that once the couple is out of camera view, the two can't keep their hands off each other, and that Britney hasn't looked this happy for a long time!

Brit, with her boytoy at her side, partied the night away at the grand opening of the new Hollywood hotspot, Sideways Restaurant and Lounge. Well, a girl does have to eat and drink, and dance, and smoke!

Luckily, Spears' strategically placed arms helped keep this photo op rated PG. Maybe you can teach an old dog new tricks!

Richie was sporting a Band-Aid, uh, white bikini, tied around her neck and at the sides. Madden, playing the role of "too hardcore for the beach," was dressed in gothish head-to-toe black, highlighting his hideously tattooed arms and legs.

Not only has former SNL funnyman Chris Kattan gotten engaged to a woman, but his fiancee is a hot model!

Chris and his soon-to-be bride, Sunshine Tutt, were caught having lunch in West Hollywood over the weekend.

Although Halloween is nine months away, the duo arrived in Puerto Vallarta dressed in their standard costumes. Nicole in her Rhoda Morganstern meets vagabond gypsy chic and 27-year-old Joel in his usual suburban high school wannabe rebel gear. ¡Ay dios mio!

We know about Joel Madden, but what's up with the rest of Good Charlotte? --David

Yes, David, we do know the latest on Joel Madden's love life, but as far as his professional life is concerned, he and the band have been hard at work preparing for their next album. Titled "Good Morning Revival," they expect it to hit shelves around March 20.

Joel said they finished about 50 songs, realized they weren't what they thought they'd be, scratched them, and started all over again! Putting that much work into the album -- no doubt it'll be good!

Moakler and Grdina, a porn star who has starred in several adult classics such as "Encino Housewife Hookers" and "I Dream of Jenna," were spotted exiting Mr. Chow on Wednesday night. While the two kept their mouths shut when it came to their blossoming relationship, the hand holding was enough PDA to confirm that there's something going on between them. Bow chicka bow wow.

Looks like those rumors of a New Year's reunion between Shanna and her ex-hubby Travis Barker were just that.

With reports of the duo "making out" on New Year's Eve, a disheveled Simpson can be seen exiting the club with Mayer by her side.

While famous for micromanaging his daughter's career into the ground, where was Papa Joe (or Ken Paves!) with a hairbrush when she needed one?!
