For 23 years, Nickelodeon's Kids' Choice Awards has been an event in which celebrities can truly let loose. After all, it's hard to have an ego when you're getting covered in green slime or being inducted into the Arm Fart Hall of Fame (we're looking at you, Josh Duhamel).
Nick's 2011 awards show, which aired lived on the network Saturday from Los Angeles, kept with its tradition of stars finding themselves in some truly outrageous situations. [article id="1657689"]Host Jack Black[/article], who was at the helm for the third time (he last helped hand out those coveted orange kaleidoscope blimps in 2008), kicked things off with an over-the-top musical number. The funnyman, wearing a black leather jumpsuit with flames — the first of many quirky wardrobe changes — was joined by a group of dancers to perform his own rendition of the Black Eyed Peas' hit "I Gotta Feelin'."
Black then introduced the group, as the "Jack Black Eyed Peas," and joined them onstage for "The Time (Dirty Bit)." BEP, who later won the award for Best Music Group, then sang their next single, "Just Can't Get Enough."
The first award of the evening was given out to Johnny Depp, who won Favorite Movie Actor for his performance in "Alice in Wonderland." Depp, who emerged from backstage, told the kiddie crowd and voters it was "truly a pleasure to receive this award that comes from you guys. I appreciate it."
After apologizing for beating Black in the category, Depp told Nick viewers, "You guys are the future; take good care of us." The actor then proceeded to get in on the fun, sliming the group of young fans who stood at the foot of the stage.
Depp's stunt led to one of the evening's most memorable — and by far, funniest — moments when "Arthur" actor Russell Brand and "Modern Family" star Rico Rodriguez appeared onstage soon after to present the award for Favorite Voice from an Animated Movie (the blimp eventually went to Eddie Murphy, who got the crowd to sing him "Happy Birthday," for his role in "Shrek Forever After").
Before Brand and Rodriguez could even begin their banter at the podium, the freshly slimed youngsters began throwing the green, gooey mess at the two stars. In response to the mayhem, Brand declared, "I'm never having children."
Brand continued, as he guarded Rodriguez from the kiddie coup, "I am English! I am your leader! You must not do this, I am royalty! You are all going to juvenile hall. You children are going to prison. You are bad children!" Brand, who is voicing a character in the animated feature "Hop," cried that the moment was not in the script, then joked, "Johnny, I wished you'd drowned them."
They weren't the only stars to get slimed during the broadcast. Heidi Klum, who almost took a spill thanks to her sky-high heels, got hit, as did Jason Segel, who received a slime slushie courtesy of Jane Lynch. Even Snoop Doog — who joined pop-rock group and Nick stars Big Time Rush for their song "Boyfriend" — got doused in the green stuff.
As Willow Smith performed her hits "21st Century Girl" and "Whip My Hair," the 10-year-old was cheered on by her dad, Will Smith, and brother, Jaden Smith, who were in the audience.
The final big award of the evening went to [artist id="2408193"]Miley Cyrus[/artist], who won for Favorite Movie Actress for "The Last Song." The former "Hannah Montana" star attempted to put gossip to rest during her acceptance speech as she thanked her family for supporting her career.
Cyrus will no doubt get fans wondering about the status of her relationship with "Last Song" co-star and on-again, off-again beau Liam Hemsworth, whom she thanked for "helping me make movie magic" in the 2010 drama.
The Big Help Award, which was presented by Rosario Dawson, went to singer/actor Justin Timberlake for his devotion to charities, particularly the work he does with Shriners Hospital for Children. In between cracking jokes about burping and getting the crowd to cheer if they had ever helped anyone, Timberlake took the time to tell his young fans, "Your heart is the most beautiful part, so don't forget to use it."
In addition to telling kids they can do their part to help, even with major issues such as the crisis in Japan, the star said something bound to make any adult watching elated: "Listen to your parents!"
Finally, Kourtney and Kim Kardashian hit the stage to help give away the last award of the night for Favorite TV Show, which went to the kid-friendly Nickelodeon hit "iCarly."
Black kept a high energy throughout the show, including some interactions with his "Kung Fu Panda 2" character, Po, — one of which featured a cameo from Britney Spears in a pre-recorded segment. He ended the evening with a slime battle between himself and Jim Carrey, who made a surprise finale appearance.
