Nick Jonas wowed the crowd at the 2015 Nickelodeon Kids’ Choice Awards, held Saturday at the Forum in Inglewood, Calif., which seats 17,500 — screaming kids.

The host pulled double duty, kicking off the live show with a medley performance of his hits “Chains” and “Jealous.” Welcomed by a video montage of A-listers chanting his name — Taylor Swift, Heidi Klum and, of course, SpongeBob SquarePants’ Patrick Star — Jonas took the stage, in front of the star-studded audience, including Chris Pratt, Jamie Foxx and Angelina Jolie, who was joined by two of her kids, Shiloh and Zahara.

“A lot of girls in the house are still struggling after One Direction became two directions,” Jonas greeted the crowd, alluding to this week’s news of the boy band losing member Zayn Malik. Poking fun at himself, he quipped, “What’s next, the Jonas Brother?”

Emma Stone won the first award of the night for favorite movie actress. Next up, Kaley Cuoco-Sweeting and Kevin James presented Liam Hemsworth — who walked up to stage through a fountain of slime — with the orange blimp for favorite male action star. Hemsworth’s co-star Jennifer Lawrence, not in attendance, also won for favorite female action star, and “The Hunger Games: Mockingjay – Part 1” won for favorite movie.

Some of the night’s other big winners were Jolie, who won for “Maleficient”; Ben Stiller, who won for the latest “Night at the Museum” installment; girl band Fifth Harmony; “The Voice” for favorite talent competition show; Disney Channel’s “Austin & Ally” and “Modern Family,” whose entire cast was slimed when they accepted their honor for favorite family show.

“When I was little, I was told I was different,” Jolie said during her acceptance speech, picking up the award for best villain. She addressed the room of kids with an inspiring message. “Different is good. So, don’t fit in. Don’t sit still. Don’t ever try to do less than you are. When somebody tells you you’re different, smile and hold your head up high and be proud. And as your villain, I would also say, cause a little trouble. It’s good for you.”

Josh Gad, who headed to the Kids’ Choice Awards after Variety Studio: Actors on Actors, presented the blimp for favorite reality Sh ow with Adam Sandler. The comedians (not to be confused with Gad’s upcoming FX series) announced the winner, “Dance Moms,” but not before Sandler doused Gad in green goo via a gigantic slime gun.

Throughout the night, Jonas made his way through the crowd to take photos with celebrities such as Terrell Owens and Al Roker, who predicted a forecast of slime.

Jennifer Lopez was one of the show’s surprise superstars. The “American Idol” icon presented the award for favorite male singer, which went to the man of the night, Jonas.

“You deserve this and so much more,” Lopez said, bringing down gallons of slime to drench the host. “Do you want some more? Because I can make it happen!” she teased.

Chris Rock, Zendaya, Tia Mowry-Hardrict, Debby Ryan, YouTube phenomenons Bethany Mota and Shawn Mendes, and Nick Cannon, who donned an orange suit, were presenters at the KCAs.

Iggy Azalea and Jennifer Hudson teamed up to perform their single “Trouble” with the rapper dressed up as an inmate and the songstress as a cop.

Closing the night, Australian band 5 Seconds of Summer rocked out to their hit “What I Like About You” — and yes, the stage exploded with slime.
