Dancing with the Stars

She got a fair trial in the TMZ newsroom ... but Nancy Grace was officially convicted on one count of chemical warfare ... by farting in the ballroom on "Dancing with the Stars."

BREAKING WIND NEWS -- Nancy Grace claims she's been FRAMED in the "Dancing with the Stars" fart mystery ... and tells TMZ an "investigation" is underway to find out who REALLY dealt it.

Grace -- who was doing a post-dance interview on the show last night when someone let it rip -- tells us, "As an ear witness on the scene, I can absolutely exonerate Tristan, myself and Brooke."

Nancy Grace definitely cut a rug on "Dancing with the Stars" last night ... but did she also cut the cheese???

Listen closely to the clip of Nancy yakking with Brooke Burke after she waltzed to "Moon River." You'll hear what sounds like a fart escaping from someone. As far as we can tell, there are only three possible culprits.

So we ask ...

Less than three months after breaking off their engagement at the VERY last minute, Kristin Cavallari and Jay Cutler were seen holding hands in L.A. today.

Pretty shocking they would reconnect ... especially because Kristin had already taken pictures IN HER WEDDING GOWN when the two suddenly called it quits.

But the Chicago Bears quarterback was spotted in the audience at "Dancing with the Stars" last night ... and now, some P.D.A. in front of the photogs.

Not a good month for Mark Ballas -- two weeks after the "Dancing with the Stars" pro lost his hot girlfriend Pia Toscano ... some heartless burglar busted his car window and jacked his guitar.

Ballas posted the bad-luck news this weekend on his Twitter -- writing, "My car just got broke into and my first Martin guitar was taken..."

To make matters worse, Ballas says his super-expensive Breitling watch was stolen earlier last week.

On his way out of "DWTS" practice, Ballas told photogs he'll pay good money to get Marty back.

Getting booted of "Dancing With the Stars" in week one is working out just fine for Ron Artest's partner -- because Peta Murgatroyd just signed a SIX FIGURE deal to fight cellulite.

Sources close to Murgatroyd tell TMZ she's working with Adonia Organics to endorse their cellulite serum -- which claims to reduce the dreaded "c word" in just nine minutes. And, yes ... we're told Peta's killer legs will be on full display for the campaign.

Finally, an upside to cellulite.

Rob Kardashian is like one of Pavlov's dogs ... a little praise from "Dancing with the Stars" judge Carrie Ann Inaba has him thinking he's got a shot to win the whole competition.

After Rob danced the jive on Monday ... Carrie Ann said, "It's official. Rob Kardashian is a better dancer than Kim Kardashian!"

Now sources close to the show tell us Rob is hitting the gym daily, practicing harder than ever -- and sucking up to his partner/teacher Cheryl Burke by bringing her lunch each day.

Rob's new attitude is a 180 from a few weeks ago -- when he was a total slacker.

The suspicious letter containing white powder that triggered a crisis at CBS Studios today was addressed to a specific individual connected with "Dancing with the Stars" ... TMZ has learned.

While there's been controversy surrounding Chaz Bono's appearance on the show ... sources tell us the target was NOT an on-air personality or contestant.

As we previously reported, it was determined the powder in the letter was not a harmful substance.

The suspicious, white-powder-containing letter that triggered an emergency situation at CBS Studios in Hollywood today was intended for "Dancing with the Stars" ... law enforcement tells TMZ.

TMZ broke the story ... emergency vehicles were called to the studio after an unknown white powder spilled out of a letter inside the CBS mailroom.

Officials later determined the substance was not anthrax -- or any other harmful substance.

Police and emergency vehicles arrived to CBS Television City in Hollywood moments ago ... after someone reported that white powder spilled out of a letter in the CBS mailroom.

Law enforcement sources confirm ... cops are investigating the scene.

Sources on the lot tell TMZ ... the letter was NOT addressed to anyone on "Dancing with the Stars" ... but so far, it's unclear who the intended recipient was.

It's not the first time CBS has had an anthrax scare -- just last year, the studio went on lockdown when production staff found white powder in a letter addressed to Bristol Palin.

Officials also intercepted a threatening letter addressed to "Late Late Show" host Craig Ferguson just last month. The letter also contained white powder -- which was later determined to be cornmeal.

3:21 PM:The L.A. City Hazardous Materials team is on the scene.

Nancy Grace is adamant ... her nip did NOT slip on "Dancing with the Stars" last night ... and insists the object that poked out of her dress last night was merely a PASTY!

Grace tells TMZ ... "When I got dressed, I was wearing Petals (nipple covers) and an industrial strength bra ... my dancing dress also had a bra sewn into it."

Nancy adds, "I have been judged guilty without a trial ... I will go to my grave denying the nip slip."

Nancy Grace's bra has been a key factor during her performances on "Dancing with the Stars" -- not JUST for support, she's also using it to SMUGGLE various lucky charms onto the ballroom floor.

TMZ has learned ... Nancy's 3-year-old twins LOVE watching their mom on the show -- and they've been giving her various "special" objects for good luck -- including a barrette and a little stone.

But since they don't exactly make pockets on Nancy's teeny, tiny cocktail dress costumes -- she's been stuffing the items into her bra ... so they're close to her heart when she's doing her thing.

Derek Hough proved he can stomach his "Dancing with the Stars" competition by showing off his lean, ripped and hairless chest & abs this weekend.

Doing the Viennese Waltz with Ricki Lake does his body good.

There's no transgender jealousy going on between Thomas Beatie and Chaz Bono -- because everyone's favorite pregnant man told us ... he's pulling for Chaz to take home the title on "Dancing With the Stars."

Beatie, his three children, and wife Nancy were out at CityWalk yesterday -- where he told our photog he thought it was "awesome" that Chaz was doing the show, saying, "It's wonderful and it's good to see other transgender people in the media."

Call him Ron Artest, Metta World Peace, Mr. Peace -- or just ... First Guy Voted Off "Dancing With the Stars."

The Los Angeles Lakers star lost with grace -- unlike his Cha cha -- and tipped his hat to "Jerry Maguire" on his way out the door Tuesday night.

Ron Ron was joined by Nancy Grace in the bottom two.

Gloria Allred celebrated Chaz Bono's debut on "Dancing with the Stars" last night -- gender-bending her way through a transgender dance party in West Hollywood ... and the video clip is incredible.

Gloria wanted to address critics of Chaz, who claim his presence on the show is a bad influence on children.
