Hot Bodies

Buxom "Jersey Shore" beauty Jwoww has become quite the heavyweight.

While getting in some GTL time in Jersey this weekend, J's trainer used her as part of his upper body workout.

Our friends at OfficialImage.com caught the "Hellcats" star takin' a dip at Wet Republic at the MGM Grand ... right around the time Avril Levigne was celebrating her 26th birthday.

Sources involved in the negotiations confirm Hugh Hefner's people reached out with a "pretty big offer" involving a huge payday and the cover -- as long as the Mexican reporter strips down to her traje de cumpleaños.

But don't get too excited -- sources close to Ines tell us her network prohibits talent from posing in the buff.

While Shawn Chapman Holley was mum about Lindsay's rehab situation -- she claimed that if Lohan "needs" her during her new stint ... Holley declared, "I will be there."

Beep, beep, beep, beep, BEEEEEEEEEEP!!!!!!!!!!

Katy shot a segment for the show -- which was supposed to air on New Year's Eve -- in which she sings a cleaned-up version of her song, "Hot N Cold" with Elmo.

The song made its way to YouTube Monday and racked up nearly a million views. But some parents started complaining her cleavage was too front and center. We've learned producers have decided not to air the song on the show.

Among the parental comments:

-- "You can practically see her t*ts. That's some wonderful children's programming."
-- "they're gonna have to rename it cleavage avenue"
-- "my kid wants milk now"

Fact is ... what looks like Katy's bare chest is actually covered in flesh-colored mesh that goes all the way to her neck.

Courtney showed off her refurbished doll parts at a premiere in NYC last night.

The 46-year-old may have lost a daughter, but she's gained some new things too.

Our pals at Officialimage.com obtained a whole bunch of awesome photos of the singer lettin' loose at the pool at the Hard Rock Hotel.

Perry -- who was doin' some boozin' at the pool -- was clearly mentally prepared for the weekend ... dropping the following tweet before the weekend kicked off, "Signing up for a liver transplant now.”

It all went down at Dos Pueblos High School near Santa Barbara, CA -- where 25-year-old Katy claims she spotted and then singled out the "most popular kid" in her class -- then rubbed in the fact that he "never wanted to date" her.

Katy then poured salt in the wound by screaming, "What's up now?" ... and followed it up by dedicating her next song to him ... titiled, "You're So Gay."

Montana has parlayed her sex tape fame into a deal posing for Bullett magazine. And if you had "posing topless" in your Montana Fishburne Career Trajectory pool, we're sorry to tell you ... she's fully clothed!

One of the lucky bastards posing with Kristin is celeb photog Tyler Shields ... who took the pics "just for fun" ... no specific reason.
