Simply stunning!

Julianne Hough wowed on the PCA's red carpet in a backless silver sequined party dress that was cut super low at the bottom, but where was beau Ryan Seacrest?

The Footloose star isn't nominated for any awards this year, but Seacrest's American Idol won the Favorite Competition Show honor, yet again!

We're betting Miss Hough gets a PCA nomination next year for her sexy role in Rock of Ages!

Wearing a cream-colored David Koma dress with a low-plunging neckline, Jimmy Choo heels and a Marchesa bag, Miley Cyrus looked very grown up as she escorted her beautiful beau, Liam Hemsworth --sans tie -- down the red carpet at the People's Choice Awards, on Wednesday evening.

The former Disney star and her man are not nominated for a PCA this year, but Liam's big bro Chris is nominated for Favorite Movie Superhero for his role in Thor. Fingers crossed!

Miley's man will take to the stage tonight to dole out an award. The singer Tweeted before the show, "Can't wait for People's Choice with my boo today! Can't wait to watch him present =]."

Lookin' good girl!

A noticeably slimmer Demi Lovato donned a sparkly peach Marchesa gown for the 38th annual People's Choice Awards at the Nokia Theatre in LA on Wednesday night, where she's scheduled to perform live!

And Lovato didn't leave the show empty handed. She nabbed the coveted Favorite Pop Artist award tonight!

Congrats, Demi!

We're live at the 2012 People's Choice Awards, and celebs including Vanessa Hudgens and Rob Pattinson are expected to hit the red carpet any minute now!

While Katy Perry was scheduled to attend tonight, she announced earlier this week that she wasn't going to make it, but with nominees like Gwyneth Paltrow, Kim Kardashian, George Clooney, Taylor Lautner and Ryan Reynolds, it looks like the show will still be quite star-studded!

Demi Lovato and Faith Hill are set to perform .. stay tuned for more coverage and the list of winners!

While stopping at her hairdresser in Beverly Hills for a blowout, Kim Kardashian took a moment to address the rumors that are claiming sister Khloe is NOT a Kardashian.

When asked if the claims that Khloe was fathered by someone other than Robert Kardashian were true, Kim said, "That is ABSOLUTELY not true."

Robert Kardashian's ex-wife Jan Ashley claims in a new interview with Star that the late attorney is not Khloe's dad.

Ashley told the mag:

"Khloe is not his kid -- he told me that after we got married. He just kind of looked at me and said [it] like it was a matter of fact. He said, 'Well, you know that Khloe's not really a Kardashian, don't you?' And I said, 'OK,' and that was it."

Khloe didn't stay quiet. She Tweeted, "The audacity you have to mention my father’s name like this! Should be ashamed of urself! I let a lot of things slide but this one is really low,YOU ARE DISGUSTING! (yes you know who YOU are)."

Jennifer Garner was spotted at Brentwood Country Mart yesterday, and it seems like her baby bump is ready to bust out of her striped sweater!

The expectant actress was spotted at the doctor with hubby Ben Affleck the other day, and with Jen's due date right around the corner, we can only imagine how chaotic things are at home! Ben's definitely going to be picking up some extra daddy duty shifts -- either that or they're going to have to hire another daddy to take Violet and Seraphina to school!

Oh, Snooki ... we miss your signature poof!

The 4'10" Jersey Shore star, sporting a straight and maroon-streaked 'do, hit up the Gallery Nightclub inside Planet Hollywood Resort & Casino to party Las Vegas-style.

Spies inside the club say the newly slimmed-down reality starlet and her beau Jionni LaVelle were sipping on Grey Goose with OJ all night long in the VIP area.

Aside from partying, Snooki is also in Sin City for the annual Consumer Electronics Show to announce her partnership with iHip headphones.

Mo' money, mo' problems ... but in her case, it's mo' money, mo' makeup. We'll fist pump to that!

Teen Mom star Leah Messer and current beau Jeremy Calvert are expecting twins!

This will be the second set of twins for the 19-year-old reality starlet, and she learned the news last week. Even though her pals reveal that she's broke, Leah apparently believes the new twins are "her ticket to fame and fortune." A source adds, "She thinks the babies will help her get her own spin-off show ... And that means a much bigger salary!”

And get this -- the mag reports that Leah is determined to become an even bigger star than reality TV mom Kate Gosselin! “She wants her own series and her own brand, just like Kate!” the insider says.
