Rihanna Gets NIPPED at the Grammys

Under the watchful eye of CBS censors, Rihanna kept her lovely girls barely covered in a blood red gown at the Grammy Awards on Sunday.

Normally RiRi looks hot, but in this pic ... she looks a little cold.

Beyonce vs. Kelly Rowland Who'd You Rather?

With no sign of poor Michelle Williams ... Beyonce and Kelly Rowland both made appearances on the Grammy Awards red carpet.

While Bey kept it movie night casual in pants, Kelly went all out in a body-baring gown.

The question is ...

Frank Ocean Has the Grammys Wrapped Around His Fingers

Despite his injured hand from his recent fight with Chris Brown, Frank Ocean was all smiles at the Grammy Awards on Sunday.

If you were up for six Grammys, you'd be smiling too.

Jenna Jameson Keeps It PG!

The CBS censors can rest, porn diva Jenna Jameson -- with her blonde Miley/P!nk weave -- kept all of her XXX lady bits covered in a demure gold foil gown at the Grammy Awards on Sunday.

While there's no word why the hell she's at the Grammys, Jenna is known for her amazing oral skills.

Jennifer Lopez Gives CBS the Leg!

CBS fashion censorship memos be damned, her highness Jennifer Lopez showed up to the Grammys with a very high cut gown that showed off her gorgeous Jolie leg and then some.

Hey, at least it's pretty modest compared to her 2000 Versace number.

Adele Rolling in the Drapes!

Doing her best Mrs. Roper impersonation, Adele looked gorgeous in a red floral tapestry at the Grammys on Sunday.

At least it's different from her usual shapeless black ensembles, right?

Chris Brown Can't Beat a Crisp White Suit

Fresh from wrecking his car yesterday, Chris Brown showed up the Grammys -- without Rihanna at his side -- and proved he's got a lot of nerve ... to wear an all white suit.

In order to keep his outfit unblemished, everyone should stay away from Chris tonight.

Justin Timberlake Suit & Bow Tie!

Looking dapper as usual, Justin Timberlake arrived to the Grammys on Sunday wearing .... drum roll ... a suit and tie. Well, a bow tie actually.

And you thought the sexyback jokes were endless.

Whitney Houston Bro and Sister-in-Law We're Down with Clive's Party

Whitney Houston's brother and sister-in-law arrived in Los Angeles yesterday to attend Clive Davis' big pre-Grammy bash ... a bash Whitney's mom called "obscene."

Whitney's mother Cissy slammed Davis' invite, saying, "I got an invitation to the party, which is the most obscene thing. I don't know why they would want me to come to the party in which she died, you know? I guess maybe he just sent me a copy for remembrance sake."

Whitney's brother Gary -- along with his wife Pat (who was also Houston's manager) -- begged to differ and flew into LAX Saturday, telling us they were going to "support Clive."

Houston was found dead in her hotel room this time last year, just hours before Davis' annual party just floors below.

Grammy Wardrobe Censorship You Be the Judge

CBS has put the screws to the fashion risk takers who want to show some skin at tonight's Grammys. Now that the memo is out, musicians now must decide whether to dial back. So we gotta ask ...

The Grammys are mostly about

J.Lo vs. Toni Braxton Exposed Grammy Diva Would You Rather?

With CBS trying to put the kibosh on everyone's favorite genital revealing outfits at the Grammys this year, who can forget the two visionary pop divas that helped ignite the NC-17 overexposed lady bits chic craze: Jennifer Lopez in her infamous plunging Versace poolside coverup back in 2000 -- and Toni Braxton's Caligula-era torn sheet dress thing from 2001.

Question is ...

Stevie Wonder Supports Grammy Prudes No Thongs? No Problem!

0-se8izbvx

Stevie Wonder says he totally backs CBS' push to ban risque clothing from The Grammys ... then again, he really doesn't know what he's missing!!!

Wonder was leaving The Sayers Club in L.A. last night when we asked about the network's email to the stars -- urging them to cover up their butt cracks, boobs and special no-no places for Sunday's big show.

Stevie told us he completely understands CBS' anti-skin efforts ... saying, "Children watch it too, ya know?"

The Grammys Celebrities Warned ... Keep Your Genitals Covered!

CBS doesn't want to see a SINGLE celebrity butt crack at the Grammys on Sunday ... and no boobs or genitals either ... this according to a warning the network fired off to all "talent" appearing on the show.

The email -- which surfaced online -- was sent by CBS Standards and Practices to people connected to the celebrities who are expected to appear on camera during the broadcast ... and the network makes it clear, it's not taking any chances with the FCC this year.

"Please be sure that buttocks and female breasts are adequately covered," the letter reads.

"Thong type costumes are problematic. Please avoid exposing bare fleshy under curves of the buttocks and buttock crack."

It goes on ... "Bare sides or under curvature of the breasts is also problematic. Please avoid sheer see-through clothing that could possibly expose female breast nipples."

"Please be sure the genital region is adequately covered so that there is no visible 'puffy' bare skin exposure. Please avoid commercial identification of actual brand name products on T-shirts."

"Foreign language on wardrobe will need to be cleared. OBSCENITY OR PARTIALLY SEEN OBSCENITY ON WARDROBE IS UNACCEPTABLE FOR BROADCAST. This as well, pertains to audience members that appear on camera.'

But the most shocking part of the letter, CBS does not want talent to wear a lapel pin or any other accessory which contains the name of an organized cause "visibly spelled out."

So, a star can wear a pink ribbon ... as long as it doesn't say "The American Breast Cancer Foundation."

We reached out to CBS -- so far, no word back.

The Canyons SNUBBED By Sundance

The producers of Lindsay Lohan's film, "The Canyons," are stunned that their flick has been rejected by The Sundance Film Festival and they think it's largely Lindsay's fault.

We're told the Sundance people reached out to producers to screen the movie, and we're told producers were led to believe it was a shoo-in.

But we found out Sundance passed on the film recently, and the film's producers believe it might be due in part to the hijinks of its troubled star. They think Lindsay was a "turn off" to the highfalutin Sundance folks.

"The Canyons" producer, Braxton Pope, tells us his agents William Morris/Endeavor are having a screening for buyers at the end of the month and a number of big companies are interested.

We also spoke with Lindsay's co-star -- porn star James Deen -- who tells us he's not bothered about the Sundance diss ... saying, "It coincides with AVN (the porn awards). Priorities man!!!!!"
