On the surface, Justin Bieber and Eminem have about as much in common as Heidi Montag and Mother Theresa.

Bieber doesn’t have any children, hasn’t penned any threatening lyrics about his ex-wife and has never entered rehab for a painkiller addiction.

But the 16-year old is considered by many to be the world’s biggest pop star, while Eminem has often enjoyed the same recognition within the rapping community.

Need more similarities? Both stars have also released albums that have dominated the music charts, and, ummm, they’re Caucasian.

They might also both anchor biopics, as Bieber tells the latest issue of Teen Vogue: “We’re trying to set up a movie for me in the near future – it’s going to be similar to the story of how I got discovered. Kinda like my own version of 8 Mile.”

Bieber didn’t say that he’ll star in the film, but this weekend’s Saturday Night Live gave us a glimpse at his burgeoning acting skills. They aren’t shabby.

Ke$ha dissed Britney Spears earlier this month for her lip syncing tendencies. But the mouthy upstart also gave props to the princess of pop in an interview.

In her chat with So You Think You Can Dance Australia, Ke$ha talked about her song “Styrofoam,” and its lyric “In 10 years, Britney Spears. Britney, who?”

Another apparent diss? Maybe not. “Just to clarify, I didn’t write that bit,” Ke$ha said, “I was 15, and there is a reason that song’s not on my record. I have to admit now I ever regret even singing that because I have mad respect for her.”

Ke$ha also Tweeted an apology to Justin Bieber for that joke she made about breast feeding him in Maxim, writing “dear justin b i am so sorry if my bad joke hurt your feelings. u r obviously talented and i never mean7 to offend u. i think u r rad.”

Aww. Ke$ha has gone soft on us!

Ke$ha respects the pop goddess that is Britney after all.

Meanwhile, Britney Spears and her agent/boyfriend Jason Trawick were seen leaving his place Tuesday. Looks like all those breakup rumors were ... rumors.

Which is a good thing. First Ke$ha's apology and clarification, now a sighting of a happy Spears with her boyfriend? A very good day to be on Team Britney.

Follow the jump for a video of Ke$ha giving her props:

Loredana Jolie, one of Tiger Woods' many mistresses, is supposedly writing a tell-all book about his wild sexual encounters. With her, and with other dudes.

The woman, who also goes by Loredana Jolie Ferriolo, claims she witnessed Tiger in gay encounters and that he "had sexual relationships with other men."

The shocking twist is something none of Tiger Woods' women have claimed so far, and there has been no evidence to suggest it's true. Still, scandalous!

According to reports, Loredana Jolie recently attempted to sell her story for $1 million and described group sex that included incidents of Tiger with men.

That sure would cast the "King of Swing" in a new light ...

Loredana Jolie claims Tiger Woods also had sex with men.

Loredana says she plans to spill about how she and Tiger "came about, his healthy appetite for arranged sex, threesomes, girls next door and girl-on-girl."

Awesome. She also promises to "answer rumors surrounding Woods' sexuality." We didn't realize there were any. Guy bangs waitresses, end of discussion.

We imagine the gay sex angle is part of Loredana's quest to score a huge publishing deal, how unlikely it seems. Not that he has much credibility either.

Loredana has kept a low profile since being named as a Tiger mistress but "is in talks with a number of publishing companies," according to reports.

The gorgeous blonde from

Sicily, has told people she was "one of Tiger's favorite mistresses." She was a Playboy model and a rumored prostitute. Hot!

Quite the day for Tiger Woods gossip. Earlier, a woman named Susie Ogren told the Enquirer she saw Tiger doing ecstasy, but he didn't bed her, amazingly.

Real, concocted or somewhere in between, information about Tiger Woods' affairs has been trickling out for months ever since his sordid double life was exposed.

But Mark Seal's article in the new Vanity Fair takes the examination into the golfer's shady dalliances to a new level with interviews from four of Tiger's women.

VF explores how the world's greatest and most famous athlete got to such a reckless, shamelessly addicted and confused point in his life. Excerpts below ...

A cheapskate

With many of his mistresses, Woods was allegedly exceedingly cheap. Mindy Lawton says the only thing he ever bought for her was a chicken wrap from Subway.

Tiger and Jamie Jungers broke it off, the mistress claims, when he refused to help her financially. Of the women interviewed, Woods spent money on only one:

Loredana Jolie Ferriolo (above), a Playboy model and hooker he met through madam Michelle Braun, went on $15,000 shopping sprees and charged everything to him.

Guess when you're paying for the sex anyway ...

A degenerate gambler

Woods’ preferred place to stay in Las Vegas was the Mansion at the MGM Grand, where a one-bedroom suite costs $5,000 per night and he'd gamble in the exclusive VIP casino nearby. According to a source known as Robin Hood 702:

“Sometimes the only people were me, Tiger Woods, and Michael Jordan. Each of us sat at a private table and played big. Tiger plays big. Up to 30 grand a hand … when you’re playing splits and doubles, you can have 150 grand on one hand.”

Tiger's enablers

Woods said in recent interviews that no one in his inner circle knew about his affairs. Come on. Jamie Jungers says, “Every time I would fly out to see [Tiger] or schedule itineraries or anything, I would always go through Bryon Bell.”

If you believe Joslyn James, she also went through Bryon.

According to another mistress, Lawton (pictured), when she alerted Tiger to the fact that The National Enquirer had caught on to their affair, he put her in contact with his agent, Mark Steinberg, who allegedly replied, “We’ll take care of it.”

Tiger Woods cannot be stopped when he pursues something he wants, such as major golf championships or intercourse with Mindy Lawton at 5:30 in the morning.

A dirty individual

Lawton says she met Woods at 5:30 one morning before he had to leave for a tournament. She was menstruating, but he insisted on having sex with her, and when the key card to his office didn’t work, he drove to a nearby parking lot.

There, they had sex in his car.

After they left, Lawton claims, reporters from The Enquirer picked up the tampon she had dropped in the parking lot and threatened to use it as part of a story.

“That’s when the cover-up, happened,” Lawton recalled, referring to Tiger’s people agreeing to have him give an exclusive interview to the Enquirer's sister publication Men’s Fitness in exchange for the story of their affair being scrapped.
