Grammy Awards

The 90's were on and popping again Friday night in L.A. during Dr. Dre's pre-Grammy Party ... but nothing was cooler than Puff Daddy reuniting on stage with his former protege Ma$e.

Diddy and Ma$e killed a stellar set of a songs including "Been Around the World" and "All About the Benjamins" at the Belasco Theatre ... but their rendition of "'Mo Money, 'Mo Problems" was off the charts.

Eminem hit the stage later in the evening with Dr. Dre ... who also reunited with Blackstreet to perform "No Diggity."

It was all that and a bag of chips.

Davey Havok -- lead singer of the band AFI -- says he's BLOWN AWAY Kanye West would actually bitch about his Grammy nominations ... 'cause music isn't a competition for petty awards.

The rocker was leaving Chateau Marmont last night ... and we asked about Ye's latest outrage over his measly TWO Grammy noms this year.

By the way, Davey's never been nominated -- but somehow has a way better grip on how to handle Grammy glory, or in Kanye's case ... disappointment.

Drake has pulled himself out of tomorrow's big Grammy Nominations Concert in L.A., TMZ has learned ... and it's all because the guy claims he's got a last minute "scheduling conflict."

The show had been promoting the rapper as one of their big acts since October ... but a rep for Drake tells TMZ something came up, and now he won't be able to attend.

"Unfortunately, due to scheduling complications, Drake will no longer be performing ... [he's] currently in the middle of his nationwide 'Would You Like A Tour?' and sincerely apologizes to his fans that he can’t be there."

According Drake's website, he's not scheduled to perform anywhere on Dec. 6th ... though he does have a show the following day in Missouri.

So, why the sudden conflict? We asked the rep ... but didn't get an explanation.

It's Billie Jean vs. Titanic, and AEG claims the ship wins hands down. Translation -- AEG is trying to convince the Michael Jackson jury that Celine Dion is bigger than MJ.

AEG exec John Meglin is on the stand in the wrongful death case, scoffing at the Jackson family's claim that Michael would have earned $1.5 billion had he lived.

Meglin told the jury it's his opinion Celine is a bigger star and therefore more bankable than MJ ever would have been. Yet according to reports, Celine is worth a measly $400 mil.

Fun facts: Jackson ranks #3 in most albums sold worldwide -- more than a billion (behind the Beatles and Elvis) . Celine ranks #9 at 200 million albums.

Beyonce shaking it on stage ... the L.A. Sparks ... the B.E.T awards ... all events Grammy Crasher Vitalii Sediuk won't be seeing in L.A. anytime soon -- because he's been BANNED from L.A. LIVE.

Vitalii -- the prankster who ruined Adele's big moment when he ran on stage during the Grammy Awards this year -- faced up to 6 months in jail for his crime. But according to court docs, he copped a plea deal with prosecutors on June 20th and won't spend a day behind bars.

Instead Vitalii was sentenced to 3 years probation AND banned from L.A. Live -- the entertainment complex where the Grammys (and many other glorious events) are held.

And in case you forgot ... this is the same guy who tried to kiss Will Smith on the red carpet in Moscow and gave Madonna a bouquet of hydrangeas -- her "most loathed" flower.

All we can say is, Madison Square Garden: watch your back.

He's pranked Madonna, Will Smith and Adele ... but his next victim could be his cell-mate Bubba.

Vitalii Sediuk faces jail time for crashing the Grammy Awards stage and messing with Adele's moment at the February ceremony ... TMZ has learned.

The 24-year-old Ukranian ran onstage ahead of the singer's acceptance speech and spoke into the microphone before Jennifer Lopez shooed him off. He's been charged with entering a performance area and interfering with performers ... both misdemeanors ... and faces six months in jail and a $1,000 fine for each count.

He'll be arraigned May 31.

Remember -- this is the guy who tried to kiss Will Smith on a red carpet in Moscow ... and got slapped down for it. His first trick was to hand Madonna a bouquet of hydrangeas -- knowing full well that they are the Material Girl's "most loathed" flower.

Wonder if he has any pranks involving soap on a rope.

If he could go back in time, singer Miguel STILL wouldn't give Frank Ocean a standing ovation for beating him at the Grammys ... telling TMZ, it's just his competitive nature.

You'll recall, Miguel lost to Frank for Best Urban Contemporary Album at the Grammy Awards this year ... and while everyone stood to clap for Frank, Miguel remained seated. Chris Brown also lost to Frank, and remained seated as well.

Miguel was out in L.A. yesterday when we asked if he had any lingering feelings of guilt for dissing Frank ... and let's just say, he wasn't feeling too apologetic.

Justin Bieber isn't taking too kindly to being told he doesn't deserve a Grammy -- going after the Black Keys drummer who insulted him ... saying, the drummer "should be slapped around."

Bieber added "haha" at the end of his statement -- which he posted on Twitter -- like he was joking.

TMZ broke the story ... BK drummer Patrick Carney mocked Bieber's Grammy snub after the awards on Sunday -- telling TMZ, "He's rich, right? ... Grammys are for music, not for money ... and he's making a lot of money."

Grammy count -- Black Keys 7 ... Bieber 0

The moron who crashed the stage at The Grammys -- only to get kicked off stage by Jennifer Lopez on live TV -- was arrested for trespassing directly following the awards show ... and it's not the dumbest stunt he's ever pulled.

The idiot who wound up in handcuffs is Vitalii Sediuk ... the same dumbass who got slapped in the face by Will Smith last year (and rightfully so) when he tried to surprise the actor with a kiss on the lips on a red carpet.

During the Grammys, Sediuk somehow weaseled his way backstage ... and when Adele was announced as the winner for Best Pop Solo Performance ... Vitalii rushed to the podium and tried to grab the mic from presenter Jennifer Lopez.

Sediuk managed to get out a few words ... saying, "Thank you, Adele. You’re my inspiration” ... but Lopez quickly ripped the mic back and shooed him offstage.

Directly following the show, cops arrested Sediuk for trespassing -- and he spent the night in a jail cell ... this according to the Hollywood Reporter.

Sediuk told THR he's just a prankster and meant no harm -- adding, "I’m not a crazy guy. I just think differently."

Chris Brown had another Grammy weekend filled with drama -- but at least no one was arrested this time ... or beaten. Baby steps.

Katy Perry's giant TA-TA's ... Alicia Keys' underboobs ... Kelly Rowland's twins ... turns out they were all given the stamp of approval from CBS -- despite the network's previously harsh warning to keep the nakedness to a minimum.

Despite these revealing outfits -- and several more -- a rep for CBS tells TMZ, "All wardrobe selections passed our standards, if only barely."

You'll remember … CBS issued a memo urging everyone in attendance to cover up or else -- saying in part: "Please be sure that buttocks and female breasts are adequately covered. Thong type costumes are problematic. Please avoid exposing bare fleshy under curves of the buttocks and buttock crack."

If this is the music biz covering up ... count us in!

Rihanna and Chris Brown's new romance has already gone to pot -- the couple celebrated CB's zero Grammy wins by hitting up a Hollywood nightclub last night ... and lighting up what appears to be a joint.

Chris and Rihanna -- who won her 7th Gram last night for her "We Found Love" music video -- dropped by Supperclub for a private party ... and according to sources inside the venue, the whole place was filled with pot smoke.

It's the first time the couple's been together on Grammy day since 2009 ... and we all know what happened then.

And there's this -- Chris was shot driving away from the club with Rihanna in the passenger seat at around 3:20 AM ... which would be a big issue if he's driving under the influence of pot -- a big issue because he's on probation for beating his passenger to a pulp.

Justin Bieber has no business winning Grammys -- at least according to a guy who cleaned up at the award show last night ... Patrick Carney from The Black Keys.

Patrick was swarmed by fans outside Chateau Marmont when we asked if Bieber should feel snubbed -- seeing as how he didn't get a single Grammy nomination this year -- and he simply said, "He's rich, right?"

Then the Keys' drummer threw a major jab, adding ... "Grammys are for like music, not for money ... and he's making a lot of money. He should be happy."

He might have a point -- Justin's never won a Grammy, and does seem pretty happy ... with his Ferraris, Lamborghinis, and such.

Chris Brown handled his Grammy defeat to Frank Ocean last night with dignity and class ... KIDDING!!! ... he was totally disrespectful.

Ocean edged out Brown and Miguel to capture the award for Best Urban Contemporary Album. While most people stood and applauded Ocean ... Brown stayed in his seat -- which just happened to be front row and center, in clear view of the cameras.

It's worth noting ... Miguel didn't stand to congratulate Ocean either.

Chris Brown and Rihanna got nice and close during Sunday night's Grammy Awards.
