Joe Jonas must have really impressed Britney Spears!

The middle JoBro is joining Brit Brit for her entire European Femme Fatale tour, according to People.

Starting October 16, Joe will open for his childhood crush overseas. If you weren't official jealous of him before (you know, when he was dating Taylor Swift, Ashley Greene or Demi Lovato), the kid is now actually having a dream come true. He tells the mag:

"She was the first girl I ever had a poster on my wall of, and her album was the first CD I ever bought. It's so funny to think I had that on my wall and here I am about to perform with her."

Seriously. Jealous.

Joe will join the "I Wanna Go" singer for her nine dates in Sweden, Germany, the Netherlands, France, Ireland and the United Kingdom. This is in addition to the announcement last week that he'd be opening for Britney's New Jersey show August 5.

His first solo album, Fastlife, drops October 11.

Kate Bosworth's new man, director Michael Polish, is sexy ... however the green hair tips, not so much.

The 28-year-old actress, who recently broke up with True Blood's Alexander Skarsgard, was all smiles at Wednesday night's Coldplay concert at the Los Angeles Tennis Center at UCLA.

But what's with the green streaks? Guess Mr. Polish is a fan! Turns out Kate's new beau is directing her in the upcoming movie Big Sur based on a Jack Kerouac novel.

Now that Kelly Osbourne is a true fashionista, the E! Fashion Police host is comfortable ripping the ever-so-stylish Kate Middleton.

While sitting down with Jay Leno on The Tonight Show, Ms. Osbourne puts Prince William's wifey on blast for wearing the same dress twice. Talk about a royal faux paus!

Kelly tells Jay:

“If I am going to be the future bloody Queen of England I'm going to wear that dress once because I'm giving up the rest of my life, all of my privacy, at least I can get a new dress every day.”

Now, now Kelly! Watch what Ozzy's daughter had to say about Amy Winehouse's death ... after the jump.

Pamela Anderson is grilled out nicely ... in her white tee.

Our photogs snapped some pics of Pamela Anderson in Malibu on Wednesday (left and above), and for the fourth time in recent weeks we caught her in a weird, over-sized white T-shirt "dress."

Whether it's flip-flops or boots, Pam always pairs her tee with tan footwear.

But other than an appropriate color palette, Pam was a bit of a general mess -- not only was she wearing this get-up again, she also had a strange bruise on her forehead -- what happened?!? -- and, her tee is 100 percent see-through.

We can see her bra and her g-string (see photos in our gallery below.) Two words, Pam -- "nude underwear."

High School Musical buddies Vanessa Hudgens and Ashley Tisdale had the same idea Wednesday - hit the gym, stat!

Vanessa, who's been working her short 'do for a few weeks now, let her tee do the talking as she left an LA Fitness gym in Hollywood. "Peace off" is better than flipping the bird, right? We kind of love that she's hydrating with a bottle of Perrier - how fancy!

Though she wasn't working out with her pal, Ashley also went to the gym, wasting no time after her weekend getaway with BF Scott Speer and friend Julianne Hough in Miami. Back in Cali, she hit up the Equinox gym in West Hollywood before getting her nails done and heading off to the Phineas and Ferb The Movie: Across the 2nd Dimension premiere in Hollywood. To get even more inside scoop on Tis' fab style, check out our story on Cocktail Confession.

So did a gym trip do Ashley good? Find out ... after the jump.

We're a little bit worried for Kellan Lutz's movie career.

Since Twilight, we don't think Kellan has made a single movie in which he hasn't taken his shirt off.

Even in the abysmal romantic "comedy" Love, Wedding, Marriage (you don't remember it? you're not alone), he went shirtless. Kellan's acting in the "comedy" did get laughs from the crowd during the flick's premiere ... unfortunately, the laughter was during his dramatic scenes.

Now, Lutz is starring in Arena, a movie in which he has to fight for his life -- and people vote on whether he should die online. (Feels an awful lot like we've seen this movie before -- Gerard Butler's 2009 flick Gamer.)

The only thing that excited us about this trailer was Samuel L. Jackson dancing. See it at the 01:25 mark.

Beyonce is approaching 30 and the "Bootylicious" diva has never looked better!

The "Run The World" singer, who will celebrate her birthday on September 4, looks breathtaking in Harper's Bazaar UK's Strictly Sexy issue.

In the seductive spread, Jay-Z's wifey wears everything from Hermes to Lanvin. Stunning!

When asked about her friendship with Gwyneth Paltrow, Beyonce tells the mag:

"She pushes her boundaries all the time. You go to her house and she makes you feel like you never want to go home. She is what I strive to be one day."

Halle Berry's daughter Nahla just gets cuter and cuter by the day!

The gorgeous actress picked up her baby girl - who was clinging tightly to her caterpillar art project - at school Wednesday before meeting up with boyfriend Olivier Martinez at The Little Door restaurant in Los Angeles.

It was a really warm day in L.A., so we love that Halle wore a non-fussy white strapless jersey dress to run errands. Equally as cute? Nahla's quick change from a playground appropriate teddy bear tee, cargo pants and sneakers ensemble to a sweet white-and-black printed floral dress for lunch at the fancy café. Adorable!

While Halle and Nahla made the streets their own personal runway, Olivier kept up the role of doting boyfriend. He picked up a baguette and payed the valet before leading the way to the car. It's not often that we see all three together, so it's nice to see them looking like a happy little fam.

See video of the three getting ready to head out after lunch ... after the jump.
