If you were just looking at her ass, you'd swear the girl hanging with Kris Humphries on the beach yesterday was his ex Kim Kardashian. But from the front ... she's NO KK. Not even close.

Kris and the mystery brunette were spotted in Miami, but when they got wind of the photogs ... they quickly went in separate directions. A sign of new love?

Sources close to KH say, no -- the chick is just a neighbor who happened to sit down next to Kris ... but they're not dating.

The male goombas of the "Jersey Shore" cast continued their integration back into the wilds of Seaside Heights by riding a roller coaster on the boardwalk this weekend ... perhaps the only instance anyone will be seen getting high this season.

Mother-to-be Snooki, thank God, did not partake in the ride ... choosing to soberly walk the streets with her fiancé/baby daddy instead.

As TMZ first reported, with Snooki pregnant and The Situation on the wagon ... the gang enjoyed their first night at a bar, but no one touched a drop of alcohol.

A beefier and hairier Adam Levine showed off his still buff and inked up moves like Jagger while in Hawaii the other day.

The scruffy 33-year-old enjoyed some down time from getting along, er, splendidly with his fellow "The Voice" judge Christina Aguilera to bask in the warm sun of Kauai.

Being quite the ladies man, you can bet the Maroon 5 singer got lei'd.

Maria Shriver, Arnold Schwarzenegger and Arnold Schwarzenegger's goatee all came together yesterday to pose for a picture with son Patrick at his high school graduation.

"90210" hottie AnnaLynne McCord cooled off on a warm summer day in L.A. by sucking on the luckiest ice cold popsicle in the world at the beach on Thursday.

Lindsay Lohan has gone to the dark side ... as she begins production on her new Liz Taylor film.

We got this pic of Lindsay taking a cigarette break during a pre-production photo shoot and lighting test.

Lindsay reluctantly had her hair cut and dyed to mimic Taylor.

Snooki is no stranger to losing her balance and falling on the floor, but this time alcohol wasn't what caused her to almost bite it ... it was her huge platform wedge heels.

While arriving with all her crap to the infamous Seaside Heights crib -- where she won't be living this season -- the pregnant "Jersey Shore" star lost her footing, but luckily recovered avoiding any sort of injury to herself or her unborn baby.

The "Jersey Shore" gang's all here -- well almost all ... as Snooki, the Situation, Deena and a once again lip-locked Ronnie & Sammi made their way back down the shore to start taping season 6 (SIX!) of the trash-tastic show.

While Jwoww, Pauly D and Vinny have yet to show their over-bronzed faces, the fist pumpers may soon be joined by a new cast member ... in the form of the unborn baby boy inside Snooki's womb.

As TMZ first reported, Snooki won't be shacking up with the rest of the boozy bunch -- or with newly sober Sitch -- while she's pregnant, opting to get a place nearby instead.

With Kim, Khloe and Kourtney nowhere to be found, Kris Jenner's youngest daughters Kylie, 14, and Kendall, 16, enjoyed having the spotlight and some bikini tanning time in Hawaii on Wednesday.

Kylie and Kendall know keeping up with the Kardashian glow takes work.

Police in Norway are on the verge of declaring a state of emergency in Oslo, after tens of thousands of unruly Justin Bieber fans overran the city -- and now, they're begging the singer for help.

Justin's scheduled to perform 4 new songs tonight outside Oslo's famed opera house as part of his "Around the World" TV special -- and we're told crazed Bieber fans from all over Europe have descended on the city for the event.

We're told the crowds have swelled to such overwhelming numbers, the police lost control -- and are pleading with Bieber to take the stage early ... before all hell breaks loose ... as in RIGHT NOW.

Bieber's aware of the situation -- he just tweeted, "...for the show to happen u must all listen to the police. we are all concerned for your safety and i want what is best for u. please listen."

Bieber is currently in a secret location and will be helicoptered to the stage.

Story developing ...

Mark Zuckerberg desperately needed to refill his wallet in Italy yesterday -- stopping by an ATM on the island of Capri ... after losing $1.5 BILLION on his plummeting Facebook stock ... in a matter of hours.

Facebook shares dropped 9.6% yesterday, finishing at a new low of $28.84 -- reducing Mark's net worth from $16.2 billion to $14.7 billion. All told, yesterday's drop raised the stock's losses to 24 percent ... making it the worst-performing large IPO in the last decade.

Yesterday's drop also cost Mark his spot on the world's 40 richest people list.

Ousted "X Factor" judge Nicole Scherzinger refused to take a stand on Britney Spears this weekend in Italy -- dropping to her knees while sunning herself on vacation with her Formula One driver boyfriend Lewis Hamilton.

Who are we to judge?

Mark Zuckerberg and Priscilla Chan paid a visit to the Sistine Chapel in Vatican City over the weekend ... where they gazed at one of the most famous works of art in the history of the world -- The Creation of Adam, courtesy of Michelangelo.

Mark looked duly impressed, but we gotta ask ...

Mark Zuckerberg ditched his hoodie for a more grown up, married look ... as he and Priscilla Chan strolled on a cobblestone road on the Amalfi Coast in Italy.

It's the second leg of their honeymoon -- they just left Rome.

Good to see Mark smiling, in spite of the fact that his fortune sank from $20 billion to around $17 billion.

Halle Berry went au naturel at the beach this weekend -- not in a topless way -- but in a badass 70s hairstyle kinda way.

Halle and fiance Olivier Martinez took a romantic stroll ... and flashed her massive emerald engagement rock in Malibu.

Halle's been very vocal about her desire to move to Olivier's native France ... partially to escape the paparazzi in Los Angeles -- but she looked pretty chill this weekend, sporting her curly 'do.

Mark Zuckerberg and Priscilla Chan blended with the crowd during their honeymoon in Rome -- as best as a gazillionaire can blend.

It looks like they didn't attract much attention -- in fact, they seem to go unnoticed by most people in the crowded restaurant in the middle of the famed city.
