Paris Hilton and her boyfriend River Viiperi attended the 5th Annual Gala Benefiting the European School of Economics Foundation "Family Business Dynasties" in New York City last night, and the two looked amazing when they posed for a few snapshots outside.

And yes, the lovebirds coordinated their outfits! River tweeted a pic of himself on the way to the event and wrote, "Picked the blue one, matches better with my baby Paris Hilton's dress #Ready."

River and Paris weren't the only ones who dressed to impress! P's little sister Nicky took our breath away in this stunning red gown:

She may not be the most glamorous star, but she does look like a lot of fun!

Michelle Rodriguez dined at Madeo in West Hollywood on Wednesday night, and after her meal she flashed photographers a series of silly faces while she waited at valet.

M-Rod is back to work on the sixth installment of The Fast and the Furious, as she was snapped doing a few re-shoots with Vin Diesel and company in Los Angeles over the weekend. She'll also be back on the big screen as Luz in Machete Kills, so we're definitely looking forward to seeing more of her in 2013!

Hot mama alert!

Drew Barrymore left newborn daughter Olive at home for a night on the town with pals last night at Spago in Beverly Hills, and the actress looked beautiful in an all black ensemble that showcased her post-baby body!

Earlier in the night, the Big Miracle star attended the Rodeo Drive Walk of Style event honoring BVLGARI.

Rumor has it that Miss Barrymore is still struggling to lose the baby weight, but we don't know if we believe it! She looks better than ever!

"She thought it would just peel off, but that hasn't been the case. Drew weighs about 150lbs now, which is very high for her. Jennifer Aniston hooked Drew up with her personal yoga instructor, Mandy Ingber, and she also convinced Drew to sign up for Pilates classes twice a week. Drew is back on a vegan diet. She says it's bland and boring, but she doesn't mind if it means getting her old body back soon," sources claim.

Let's hope Spago had a vegan dish that fit her dietary needs!

Aww, looks like someone's missing his lady love!

Kanye West was spotted at the Landmark Theatre on Wednesday night, and while you'd think he'd be thrilled with his six Grammy nominations, the rapper looked rather glum when we snapped his picture. Yeezy was nominated for Best Rap/Sung Collaboration and Best Short Form Music Video, and he received two nominations for Best Rap Song and another two for Best Rap Performance.

Lady love Kim Kardashian is currently filming her reality show in Miami, so maybe he misses her big ol' booty? Or perhaps he was bummed that she hadn't yet tweeted her congrats to him? You'd think a doting girlfriend with the tendency to overshare would have at least given her man a 140-character shout out for his Grammy nods!

Lucky lady! Spending time with both her loves!

Britney Spears reported for duty on the X-Factor set yesterday with fiance Jason Trawick in tow, and the pop princess paired her favorite turtleneck with her favorite accessory - her new puppy Hannah!

Ever the doting beau, Trawick carried the leopard print dog bed for his lady love, while she cradled her new pet in her arms. With a wedding to plan and a nonstop work schedule, we don't know why Brit Brit decided to add more responsibilities to her list, but at least her future husband can play the role of dog walker if needed!

"She is 1.8 pounds. She is a barker! She is feisty and she will let you know when she's upset. And she always wants mommy," the "Scream and Shout" singer gushed about the pup during the Pepsi PreShow Live last night.

Sons Sean Preston and Jayden James must be thrilled to have a new furry friend in the house!

Check out how glam our favorite judge looked on stage last night in a cutout Herve Leger dress!

Jada Pinkett Smith cruised through LAX with her kids in tow. We can't believe how quickly they've grown!

With hubby Will Smith nowhere in sight, Jada took charge of her brood ... and looked fab while doing it.

The Smith family just returned from their Hawaiian vacation. Welcome back, ya'll!

Apparently it was an amicable split!

Courteney Cox and pals, including director David Fincher, dined at Nonna of Italy in Hollywood last night, and after their meal they decided to pop over to the Cougar Town star's ex-husband David Arquette's nightclub Bootsy Bellows for cocktails and dancing.

The actress dressed down for the occasion in black jeans, boots, a floral top, and a blazer, and she's one bold lady to go clubbing without a stitch of makeup!

If you believe the rumors, Miss Cox isn't exactly talk show host Chelsea Handler's biggest fan! According to reports, Jennifer Aniston's besties have been feuding over how to plan the Friends star's bachelorette party, with the raunchy blonde keen to have a wild bash and the brunette beauty favoring a more low key occasion.

"It's ridiculous. Chelsea and Courteney have never managed to bond, despite Jen's desperate attempts. Jen has begged them to go to dinner again - it means a lot to her that they get along. Chelsea feels she's already made the effort and Courteney just thinks she's not very mature," a source told Grazia magazine.

Talk about star power on the red carpet!

Anne Hathaway, Amanda Seyfried and the always dashing Hugh Jackman looked picture perfect at the Les Miserables premiere at the Empire Cinema in Leicester Square, England.

While Anne looked stunning in a white Givenchy gown with pearl details, Amanda rocked a black ruffled Balenciaga dress.

As for Mr. Jackman, he looked beyond sexy in his Burberry suit. Such a handsome guy!
