Paris Hilton's passport is getting more and more stamps by the day! The heiress flew to Europe to enjoy the holiday season overseas.

Princess P Tweeted the above photo and the following message:

"In #Slovenia chilling backstage with @DJAfrojack about to party & have a Good Time!"

Next year, Paris is releasing her own house album which will include the single "Good Time" that she co-wrote with her pal Afrojack. Looking forward to hearing the the tracks!

We're happy to see Nicole Richie embracing a little fashion change!

The hot mamma of two, who recently celebrated her one year wedding anniversary with hubby Joel Madden, donned an edgy punk rock jacket over her usual workout attire, as she left the gym Thursday afternoon.

In other news, Miss Richie is about to go into business alongside the Kardashians!

Kendall and Kylie Jenner have just landed a massive deal with Pascal Mouawad's Glamhouse, a jewelry company that is also home to Nicole's House of Harlow 1960 line.

In a press release, the girls said, “We love accessories, and it’s amazing that we’re going to have our own line to be able to wear everyday—and for our friends to wear, too!”

Hilary Duff has had quite a stressful week!

The Beauty and the Briefcase star's pet Chihuahua, Lola, had to undergo surgery on Tuesday, after suffering with sickness for the past few months, and now Duff is forced to do her Christmas shopping at the last minute.

We caught up with the pregnant star as she picked up a doggy bag for her pup, who has been recovering at the veterinary hospital after a successful operation.

A worried Duff Tweeted before the procedure: "Could every1 (everyone) please say a prayer for my pup lola. She has surgery in a half hour! She's a strong girl but needs all good energy sent her way," before updating fans with, "she is getting rest and doing alright. hopefully I get to see my baby girl in the am (morning). Thank you everyone for the support."

Get well soon Lola!

Looking very thin, and covering his bald head with a beanie, Matthew McConaughey was practically unrecognizable as he headed to the L'Ermitage Hotel in Beverly Hills for a workout, on Thursday.

The Sexiest Man Alive shaved off his gorgeous hair and went completely bald earlier this week, and we're already missing those trademark wavy locks. Why did you have to do it, Matthew?

He was seen with a full head of hair while shooting Thunder Run in LA last weekend, so it's anyone's guess why the actor craved such a drastic hairstyle change.

Secretly, we're waiting for it to grow back!

The best way to get over a breakup is definitely a new hairdo!

Rocking a pair of $1,000 Chanel tweed and lambskin gloves, and a $1,300 Celine leather tote, Ashley Tisdale didn't look like girl who just broke up with her boyfriend, as she made her way out of the Byron & Tracey Salon in Beverly Hills with a newly cropped 'do, on Thursday evening.

The former High School Musical star had been dating music video director, Scott Speer, for the last two years, but she seems to be enjoying her newly single status.

Tisdale treated herself to a girls night out at the Jay Z and Kanye West concert on Tuesday, and celebrated pal Vanessa Hudgens’ 23rd birthday on Wednesday.

Ash also shared a Twitpic with buddy Zac Efron early this week, with the caption: "So happy to have amazing friends in my life!"

The Kardashians jetted off to Las Vegas this afternoon in a private plane, and forget traveling comfortably -- from Kim to Kourtney to Kendall, all of the ladies were dressed to the nines and sporting sky-high pumps.

Today Kim tweeted, "Good Morning! Heading to Vegas with the family to open our new store Kardashian Khaos!" Yesterday Kourtney expressed her excitement, writing, "Is Vegas ready? @KardashianKhaos grand opening tomorrow @TheMirageLV and the whole family will be there!!"

Where will they strike next?

Aww, but hopefully all the time she's spending with her youngest daughter isn't making Violet jealous!

We spotted a preggers Jennifer Garner and her adorable girls in Santa Monica yesterday, and while Jen and Sera looked nice and cozy with one another, we have to ask: What on earth was little miss V doing?!

Following his Watch the Throne concert in LA, Kanye West had no problem watching and touching Kim Kardashian at the after-party thrown by billionaire Ron Burkle.

The hip hop star "was all over her - caressing her head, touching her waist," according to the NY Daily News.

The source goes on to say:

“Kanye was eating Kim up like she was a piece of cake. I think he was dying to kiss her, but there were too many people in the room."

Although Kim attended the Kanye/Jay-Z concert with sister Khloe, mom Kris and Scott Disick ... the 31-year-old reality star went to the after-party solo.

As for Kanye's advances on Kim, the source adds, "She was totally into it."
