Mariah Carey's bikini top successfully held on for dear life as the singer climbed onto her boat off the coast of Italy today.

Damn.

It's the stuff that caused a war between Kobe Bryant and his parents -- a collection of the NBA star's tacky jewelry, shoes and jerseys -- and now it's officially up for auction.

A diamond-encrusted NBA Championship ring complete with the words "Bling Bling" engraved on the side ... prototypes of Kobe's shoes ... Bryant's high school jersey -- it's all up for sale.

As we previously reported, Kobe sued his mom to prevent her from selling the memorabilia ... claiming she had no ownership rights to the merchandise.

But Pamela Bryant -- along with her husband Jellybean -- fought back ... claiming Kobe had gifted the stuff to them over the years and they had every right to sell it.

Last week, the two sides hammered out a settlement agreement ... in which Kobe allowed his folks to sell off 10% of what they had originally tried to auction ... and the items are pretty interesting.

Here's Rihanna (left) out and about in London last night ... and Taylor Swift (right) posing on the red carpet at the MuchMusic Video Awards in Toronto.

The question is ...

What's more distracting than Joanna Krupa's giant boobs spilling out of a skin-tight gold dress? Her humungous DIAMOND ring ... a ring SO BIG it blinded half a city block (maybe) ... and we got it up close.

Our photog spotted the "Real Housewives of Miami" star Saturday night in L.A. and asked to see the massive rock on her finger, considering JK tied the knot Thursday with Romain Zago ... in a wedding that reportedly cost $1 MILLION.

You may have seen pics, but nothing can prepare you for how HUGE the radiant-cut yellow diamond is up close ... seriously, you have to see it. Even Jennifer Aniston would be jealous.

A new law banning saggy pants on the Jersey Shore has pissed off a bunch of famous rappers -- including The Game, who tells TMZ, the anti-sag movement is racist ... and tantamount to SLAVERY.

In case you didn't know, the city of Wildwood, NJ just passed a law that prohibits anyone on its boardwalk from wearing pants that sag 3 inches below the hips, exposing skin or underwear. First time offenders are subject to fines ranging from $25-$100 ... and after that, the fines go up to $200.

40 hours of community service is also a possible punishment.

Now, several rappers are speaking out against the law -- Game tells us, "N***** should sag down to their socks out there. They trying to get people to not sag, please. Can’t tell people how to wear their f***ing clothes. What time are we in? This ain't the f***ing slave days. F*** that."

He adds, "I am with the sagging movement. First five people to get fines, I will pay their tickets ... I will go there and sag cause I am a sagging Sagittarius."

Bizzy Bone from Bone Thugs-n-Harmony tells us, "Are they talking about black people? How can they do that? This is racist and ridiculous."

And for the white guy's perspective ... Mac Miller says, "I just think that's ridiculous because no one has time to do that much community service. I sag and will sag anywhere I go."

The law's scheduled to go into effect next month. You're welcome, Larry Platt.

UPDATE 1:55 PM PT -- Hot Topic just sent us a statement, saying they hold several trademarks for use of the Blackheart brand ... some going back a decade ... adding that Jett's record company never had a problem before.

"Hot Topic, Inc. takes the rights of artists very seriously, and has in fact compensated Ms. Jett over the many years in keeping with mutually agreed-upon license agreements ... this lawsuit is a surprise to us, and we are confident in our rights to use the Blackheart brand name."

Joan Jett's got her panties in a twist over a brand new line of lingerie -- owned by Hot Topic -- claiming the risque undie line completely ripped off her "Blackheart" trademark ... as well as her style ... and now her record label's out for payback.

Blackheart Records has filed a lawsuit against HT, claiming the rock-n-roll retailer jacked the "Blackheart" trademark for its new Blackheart lingerie line ... which advertises itself as "lingerie for girls who rock and roll."

Jett's record label insists Blackheart lingerie is blatant trademark infringement -- because Jett popularized the term "Blackheart" with her band Joan Jett & the Blackhearts ... and personally made the rock-and-roll chick thing mainstream.

Blackheart records is now suing for trademark infringement and more, demanding unspecified damages ... as well as an injunction blocking any further sale of the lingerie.

Calls to Hot Topic weren't returned.

Here is actor turned banjo enthusiast Steve Martin at a gala in New York this week (left) -- and Bryan Cranston's meth-making character Walter White aka Heisenberg in the television thriller "Breaking Bad" (right).

Hopefully, only one of them has a surprise ending this year.

Prince Jackson clearly knows how to compartmentalize his life ... because he hit the town Tuesday night in low fashion, attending the premiere of True Blood, Season 6.

The 16-year-old and his GF, Remi Alfalah, were flanked by 3 bodyguards as they left the ArcLight in Hollywood.

People inside the screening tell us ... they were "touchy-feely" and seemed happy. Almost everyone was dressed up -- except Prince, which either makes him a slouch or a baller.

Nicolas Cage is a man of mystery ... which is why we have NO EXPLANATION WHATSOEVER for the extra pair of sunglasses he was wearing around his neck last week.

The photo was taken inside a supermarket in Alabama, but other than that ... we got nothing. For what it's worth, he's down South for a new movie (and no, he does NOT play a four-eyed mutant).

Maybe he was holding the sunglasses for a friend, maybe he's got a second pair of eyes somewhere on the back of his head ... the world will never know.

Still ... it's not that weird considering everything else Cage has done in his life ... such as collecting shrunken heads, owning cobras, buying a dinosaur skull ... and oh yeah, the pyramid tomb.

Kate Upton's bra was battle tested yesterday ... pushed to its ultimate limits ... and unfortunately for us, it emerged victorious.

Kate was hangin' out on the set of "The Other Woman" in Westhampton, NY ... when for some glorious reason, she began to jump around ... bouncing ... and bouncing ... and bouncing some more.

In the end, the bra -- like anyone else in its position -- refused to surrender its grip.

Ferraris apparently aren't fast enough for Justin Bieber .... 'cause the singer has just been booked on a ROCKETSHIP DESTINED FOR SPACE ... so says Virgin Galactic honcho Richard Branson.

Branson himself confirmed that Biebs and manager Scooter Braun are on the V.G. manifest, tweeting this morning: "Great to hear @justinbieber & @scooterbraun are latest @virgingalactic future astronauts. Congrats, see you up there!"

Branson's venture just completed its first rocket-powered test last month, and the company is planning to start commercial flights next year -- plenty of time for Bieber to order a tacky, blinged-out astronaut suit.

Tickets reportedly start around $250k ... but it's unclear if JB is paying for the ride himself ... or if the trip will be comped.

No word on when Bieber is scheduled for lift off.

Porn star Taylor Stevens knows ... if the L.A. Kings are going to come back from an 0-2 deficit in the Western Conference finals, they're gonna need her boobs to distract the Chicago Blackhawks -- and tonight, she's READY TO STEP UP!!!

FYI -- Taylor has become a master distractor at the Kings games ... strategically sitting behind the opposing team's bench (with cans in full view) in the hopes of taking the players' minds off the game ... and it's worked in the past.

So, with the Kings' championship hopes on the line ... Taylor tells TMZ she's carefully selected her battle threads for Game 3 in L.A. tonight ... and judging from the pics, it's clear she means business.

Kirsten Dunst VIOLATED the "Jeremy Piven Guide to Rock Concerts" last night ... sporting a Tom Petty and the Heartbreakers T-shirt to a Tom Petty and the Heartbreakers concert.

Congratulations Kirsten ... you're officially "That Guy."

Shoulda watched "PCU" before the show ...

SIZE MATTERS ... and at last night's Heat-Pacers game, Justin Bieber was in the teeny weenie Jesus department compared to Flo Rida.

Justin dropped by the American Airlines Arena for Game 7 of the Eastern Conference finals, wearing his bandwagon baseball cap and Hefty-brand button down ... but the tiny Jesus really made a messiah of his outfit.

Flo Rida vs. Justin Bieber -- it's a slam dunk, right?

In her first red carpet appearance since announcing she underwent a double mastectomy, Angelina Jolie posed for pics with Brad Pitt today at the London premiere of his movie "World War Z."

In an op-ed piece for the New York Times last month, Jolie revealed she underwent a preventative double mastectomy back in February because "doctors estimated that I had an 87 percent risk of breast cancer and a 50 percent risk of ovarian cancer."

Since making the announcement, Jolie has been recovering at home in Los Angeles before taking on her next project -- directing a film called "Unbroken."

Will Smith is still fresh.

Here's the 24-year-old former rapper/television star at an event in 1993 (left) -- and 20 years later, the 44-year-old blockbuster king at the premiere of his unfortunate new flick "After Earth" in New York City this week (right).

Parents just don't understand ... how he ages so well.
