Miley and LOL co-star Douglas Booth flirting up a storm this week

Beyond the news of their split, rumors are running rampant regarding just why this seemingly happy couple is no longer together. Did Liam cheat on Miley? Did a photo of Cyrus and Adam Sevani actually play a role in this demise? It's all speculation at this point.




Did Miley trade in Liam for Douglas Booth?

But we wouldn't be doing our jobs if we didn't report on every possible explanation, so behold the latest:

Paris Hilton was arrested for possession of cocaine

According to police, Paris was the passenger in a vehicle that was pulled over outside the Wynn Hotel in Vegas, where her life-saving BF, Cy Waits, is based.

Officers noticed the car leaving a "smoke trail" and made the stop.

The driver was popped for DUI (drugs, not alcohol) and reports say that when cops searched Paris, they found her in possession of a controlled substance.

Police say tests revealed the substance to be cocaine, and that the ho-tel heiress, whose World Cup arrest for pot made headlines recently, was arrested.

Jake Pavelka and Vienna Girardi.

Doomed from the start, the happy relationship of The Bachelor star and his final rose recipient soon devolved into one of more memorable celebrity breakups of the year, culminating in an ugly, hilarious interview on The Bachelorette.

But Jake's calmed down since.

While he “absolutely” believed he'd be with Girardi for life, the upcoming guest star on Lifetime’s Drop Dead Diva says “It’s okay; everything happens for a reason.”

Now he just wants Vienna, who recently started dating a new guy, John Sala, to be happy. “I hope she goes out and breaks a million hearts,” Pavelka told People.



Vienna's moved on from Jake (right) with John Sala.

“I think she’s got some pretty realistic goals in life, and I wish her the absolute best. Hopefully she’ll find a guy she can spend the next 60 years of her life with.”

Jake Pavelka hasn’t interacted with Vienna Girardi since all the drama went down, and hopes that over time, he and his ex can even become friends despite it.

“I don’t have any hurt feelings over it,” he says. “The whole thing was tragic and it was sad but it happened and … it really is okay. We’ll probably let a little bit of time go by, but I’m sure someday our paths will cross and we’ll be friends.”

Hayden Panettiere! Happy Birthday

The adorable Hayden Panettiere turns 21 today. Break out the champagne! She can now legally enter the clubs she's already been frequenting for years!

The former Heroes star was once in the limelight a lot more.

Her show was a hit on NBC, and she was a celebrity news staple. Nowadays the Long Islander is under the radar a bit, as well as under Wladimir Klitschko.

We mean because he's like seven feet tall, not in that way.

Anyway, we've always loved Hayden and wish her a very special 21st. Here's a little tribute of Hayden Panettiere pictures to honor the big day ...

Mariotti was arrested early this morning in Los Angeles

The arrest took place at 4:30 a.m.

A former write for The Chicago Sun-Times, Mariotti is being held on $50,000 bail. In 2004, he got into a fight with a White Sox announcer who claimed Mariotti was a "fraud" for never entering the club house of the team he covered.

Spencer Pratt says he is ready to tell all.

The Hills villain and increasingly erratic character reveals that he is penning a tell-all about his relationship with ex Heidi Montag, including new details about her often tormented relationship with her mother, Darlene Egelhoff.

"My last book, How to be Famous, didn't make the New York Times best-seller list because it was in the self-help section," Spencer Pratt tells Us Weekly.

"This one is going to be totally different. I'm not holding anything back."

Thank goodness.

In July, Montag filed for divorce after one year of marriage, citing irreconcilable differences. Their divorce is expected to be finalized on Valentine's Day 2011.

She recently went on a $60,000 shopping spree, just months after filing for bankruptcy.

Naturally, however, the Real Housewife of New Jersey doesn't take any responsibility for these financial woes. In fact, she blames the public. We're the ones that made her famous, after all.

"If she wasn't on the show, this all would be much easier," a source complained to PopEater. "Everything would be settled by now, but because she is now famous everyone is using the situation to get press for themselves and humiliate her and her family.

"It's honestly got to the point where she's not sure if she wants to come back for another season."

Hey, don't tease us like that, annoying, anonymous friend!



Added this insider, in one of the more ludicrous, nauseating quotes of the year:

"Teresa is sick of everyone knowing all her private financial business. She didn't sign up to be on 'Housewives' so that everyone could look into her bank account. Millions of couples go through what they are going through, except no one knows about it. It's just not fair."
