It's too bad Katy Perry decided to back out of the People's Choice Awards at the last minute, because she was the biggest winner of the night!

The "Teenage Dream" singer made the sudden decision not to appear in the wake of her recent divorce with Russell Brand, but she still won nods in five categories, including Favorite Female Artist, Tour Headliner, Song of the Year for "E.T." with Kanye West, Favorite Music Video for "Last Friday Night," and TV Guest Star for How I Met Your Mother. Impressive!

Following close behind Perry with four awards, Harry Potter and the Deathly Hallows: Part 2 was honed with Favorite Movie, Favorite Action Movie, Book Adaptation and Ensemble Movie Cast. We're happy to see the last film in the Potter franchise go out with a bang!

Emma Stone took home Favorite Movie Actress and Favorite Comedic Movie Actress, tying with Johnny Depp, who won Favorite Movie Actor and Favorite Movie Voice for Rango.

Glee superstar Lea Michele won Favorite Comedic TV Actress, which she dedicated to "All the Rachel Berrys out there." Ellen DeGeneres was honored for Favorite TV Host. Neil Patrick Harris won Favorite TV Comedic Actor, and thanked partner David Burtka and their twins in his speech, who he joked, "should be asleep in the limo at the valet."

Maya Rudolph took the stage with her fellow honorees as they sang a Wilson Philips song onstage after Bridesmaids won Favorite Comedy Movie, while Robert Pattinson (who sat next to Hot In Cleveland winner Betty White during the show!) was on hand to accept the Favorite Drama Movie award for Water for Elephants.

After performing onstage, Demi Lovato nabbed Favorite Pop Artist, while Lady Gaga was honored with Favorite Album of the Year, and Taylor Swift Favorite Country Artist, although neither showed up to collect their awards.

Meanwhile, Kim Kardashian proved people still can't get enough of her over-the-top drama -- honoring her with Favorite TV Celebrity Star of 2012.

Check out a full list of the 38th Annual People's Choice Awards winners, after the jump!

Jennifer Lawrence, is that really you?

The Hunger Games star looked drop-dead gorgeous in a stunning blue Viktor & Rolf mini dress, Sergio Rossi heels, and Jack Vartanian jewelry, as she posed on the red carpet at the PCA's, before taking the stage to present an award with Liam Hemsworth.

The 21-year-old Oscar nom dyed her blonde hair red to play Katniss Everdeen in the upcoming Hunger Games flick, and we think the new hue definitely suits her!

Lawrence is nominated for Favorite Movie Superhero for her role as Mystique in X-Men: First Class, but unfortunately she lost out to Ryan Reynolds for his turn as Green Lantern.

Looking white hot in a 1920's flapper-style Marchesa gown, Jimmy Choo heels and Lorraine Schwartz jewels, Lea Michele already looked like a winner when she stepped onto the red carpet at the People's Choice Awards, on Wednesday night.

The 25-year-old New Year's Eve star beat out Glee costar Jane Lynch, PCA host Kaley Cuoco, Friends legend Courteney Cox and 30 Rock mastermind Tina Fey, to take home the coveted Favorite TV Comedy Actress award for her role as type-A songstress Rachel Berry in Glee.

Lea was also pumped about her special date for the night! The star Tweeted, �So excited I have my younger cousin in from NYC to be my date tonight! I�m so happy she�s here!!�

Congrats to Lea, and "All the Rachel Berrys out there!"

Va va voom!

Vanessa Hudgens pulled out all the stops in a black and gold floor-length Jenny Packham gown (one of Duchess Kate's fave designers!), paired with Casadei shoes, and a Judith Leiber bag, at the People's Choice Awards, on Wednesday.

The Journey 2: The Mysterious Island star, hit the red carpet without her new boyfriend, Austin Butler, but the pair were seen sharing a kiss earlier in the day.

What do you think of Vanessa's red carpet look?

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!
