Diddy

Thank you, Diddy. Thank you.

The rapper has, for whatever reason (not that he needed one) released a new coffee table book titled Culo, which means buttocks in Italian. You can guess what's in it.

Diddy, record executive Jimmy Iovine and photographer Raphael Mazzucco teamed up to compile an artistic, memorable 248-page pictorial expose on female butts.

Chief among them? Lady Gaga. Girl's got back, who knew!

Lady Gaga was born this way, baby. Well, sans tattoo.

Yeah. After all her ridiculous fashion over the years, who would have guessed one of the more shocking Lady Gaga photos out there would feature her wearing nothing.

“Raphael is a true artist,” says Diddy of Mazzucco, the man behind the image above.

“He relies on pure instinct, capturing a raw, natural sense of beauty through his lens that celebrates the female form. His work is passionate and powerful.”

That's a verbose way of spinning a book about asses, but we'll buy it.

Actually, no. Sadly, Pippa Middleton does not appear. Boycott it.

File this under stories you didn't see coming: Diddy is supposedly dating Cassie ... and hooking up with Cameron Diaz when she booty calls him, Us claims.

The magazine claims Diaz has recently been getting it on with Sean "Diddy" Combs, with whom she's had an on/off relationship since he wooed her in 2008.

Diddy, meanwhile, has been dating model Cassie for the past three years.

"Since then, when she's single, she'll booty call him," adds an Us insider.

The only hangup? Diddy is still dating his model girlfriend of three years, Cassie. Says a friend, "Diddy's single whenever there's a better offer on the table!"'

Nice. Apparently at NYC's Catch on October 24, the two were "inseparable" and "they had their hands all over each other," according to an eyewitness report.

Then, at last week's launch of Scarpetta in Beverly Hills, they were "making out, acting romantic," says a source. Reps for both stars they are "just friends."

We'd hope so for Cassie's sake ... and Diddy's. She might injure him.

Diddy claims he "backslid and regressed" when he went on a tirade the other night, shouting racial and homophobic slurs at a clubgoer in Atlanta.

The rap mogul is begging for forgiveness on Twitter for the outburst, which got so bad T.I. had to intervene and tell his boy to calm the heck down.

He threw ice at some guy, threatened to fight him and called him "n**ga" and a "f**got" all for drinking a rival brand of vodka. Seriously.

In his apology today, Diddy writes:

"I'm sorry for the ignorant way I repesented [SIC] myself ... I have backslid and regressed. Forgive me for my ignorance. Pray for me pls."

"I know better and I am better. I have a responibility [SIC] that I promise I will live up to. And I'm more dissapointed [SIC] in myself than you know."

"I will humble myself and learn."

The man on the receiving end, Ricky Parker, says he feels "humiliated and disrespected" and can't believe this entire fiasco erupted because he was drinking Grey Goose and NOT Ciroc vodka, which Diddy is a spokesperson for.

Neither can we. Watch the incident below if you haven't seen it:

Diddy damn near caused a melee at an Atlanta club last weekend.

Fortunately, T.I. was there to talk his out-of-control buddy down.

After the mogul and Ciroc Vodka spokesman threatened to get violent with a man in the crowd drinking a rival brand (seriously) at the BET Hip Hop Awards after-party.

Things almost got out of hand at Compound, until T.I. stepped in:

Diddy Calls Out Non-Ciroc Drinker, T.I. Intervenes

Diddy began shouting at the man, "B!tch ass n!ggas ... put that sh!t down ... put that sh!t down before I come smack that purple shirt off your ass."

It appears Diddy grabs ice and throws it at the man ... before screaming, "What the f*%k are you gonna do, b*tch? Get the f*%k out of my face!"

That's the edited version. As Diddy ranted, T.I. grabbed another mic.

First, Ben Affleck. Now, Diddy.

Tabloids are really desperate to get Jennifer Lopez back together with an ex.

A source tells BET that Diddy really wants to get back together with new newly-single ex because she is "the love of his life" and his "fantasy girl." However, friends worry that J. Lo will break the hip hop mogul's heart again, similar to how she dumped him in 1999 when he was on trial for weapons charges.

Witnesses claim to have seen Lopez and Diddy together in New York City this week, while a friend of the former says:

"Puff wouldn't be my first choice for her, but then again he was always very supportive of her sex symbol image and never got mad when she wore sexy clothes. He actually encouraged it."

For those of you unfamiliar with the rumors surrounding Jennifer's divorce, that was a direct dig at Marc Anthony. Yes, it's on, folks.

American Idol delivered a pair of contrasting, impressive performance on its first finalist results show of the season last night.

First, Adam Lambert went acoustic on an inspiring version of "Aftermath," receiving a standing ovation for his effort.

Then, Diddy Dirty Money (we think that's his name these days) took to the stage, accompanied by Skylar Grey, and gave the audience a version of the hit "Coming Home." He also gave the contestants some advice:

"I would say you get out of life what you put into it. You have to keep on practicing, keep on rehearsing... Keep God first in your life and don't stop. Don't ever stop."

Talk about a HOT party. Diddy was just celebrating his new album, Last Train to Paris, in typical Diddy fashion - a BALLER hotel penthouse packed with models.

The whole thing streaming live, too ... until things went awry.

As the camera cut to comedian Kevin Hart in a bathroom, a model lounges in the tub behind him, surrounded by candles. You know where this is going.

Bringing back images of Kramer and his Cuban cigar on Seinfeld, her hair catches on fire. Live on UStream! Hey, at least there was water nearby ...

T.I. Diddy. It's a clash of rapping titans and music moguls in this latest fashion clash from the MTV Movie Awards - and to the winner goes all the glory.

To the loser? Possibly a flurry bullets to the chest. Just kidding.

Hey, it's a fact that T.I. just served time in prison for possession of semiautomatic weapons. But he's halfway-housin' it now, and looking rather dapper.

Diddy, meanwhile, opted for a more casual look on Sunday night as he promoted his new film with Russell Brand and Jonah Hill, Get Him to the Greek.

Which of their styles worked best? You tell us below ...

Who looked more handsome last night?

Past and present co-stars Tom Cruise and Cameron Diaz are among the first presenters announced for this year's MTV Movie Awards, according to reports.

We haven't seen Mr. Crazy Pants in awhile, so that should be exciting. Hopefully there's a couch for him to jump on ... or a montage of Suri Cruise photos.

The actors will be joined on the celebrity telecast by Diddy, who is also a confirmed presenter. All this should make for an exciting, star-studded evening.

In addition, MTV has announced three new categories in this year's show: Biggest Bad-Ass Star; Best Scared-As-S--- Performance and Global Superstar.

For the first time, fans abroad will also have the chance to vote in the latter category by visiting their local MTV sites. North American fans can vote for their favorite nominees in all the categories beginning May 12 through June 5.

This year's MTV Movie Awards will be hosted by Aziz Ansari (known for some of the funniest Parks and Recreation quotes) and will air live on June 6 at 9 p.m.

Yes, Diddy is a hip hop mogul.

But in an interview with Playboy this week, the rap star focused more on his bedroom prowess than his producing resume.

For example, Diddy dished on losing his virginity at... age 13:

"I felt I was a porno star because I’d been watching porn for so long. In the Bronx you could get a hotel for an hour. I always had $20 or $30 to take a chick to a hotel. I’m proud to say I love sex. You might catch me in a porn store at any given moment. Iit ain’t nothing I’m ashamed of."

Diddy also practices Tantric sex.

"When I heard about Sting doing it, I thought, Yo, is this possible? I studied up on the breathing techniques and the focus," he said. "Now I think to myself, I cannot believe I’ve been going this long! Night is turning into day and I’m still goin’ at it."

So, ladies, do you wanna be railed all night long by this music icon? It won't be easy to please him, Diddy warns.

"She has to have poise. She has to be classy. But when we get in that bedroom she got to turn me out, Jack. She has to put a porno to shame and she’s got to be sexually open."
