Willow Smith made a grand entrance at Nickelodeon’s 2011 Kids’ Choice Awards, flying over the audience on a harness before landing onstage. The 10-year-old star started by performing her new single “21st Century Girl,” segueing into her smash “Whip My Hair” with her Warriorettes crew in a dance sequence by Janet Jackson’s former choreographer Tina Landon. Her proud father Will Smith and brother Jaden were all smiles as they looked on.

The Black Eyed Peas kicked off Nickelodeon’s 2011 Kids’ Choice Awards by performing their hits “The Time (Dirty Bit)” and “Just Can’t Get Enough.” Wearing fluorescent outfits, will.i.am, Fergie, Taboo, and apl.de.ap danced their way through a lively set, with a surprise appearance from host and comedian Jack Black. The Peas also took home the orange blimp for Best Music Group.

Willow Smith and her brother Jaden were the coolest kids on the orange carpet at Nickelodeon’s 2011 Kids’ Choice Awards at USC’s Galen Center in Los Angeles on Saturday (April 2). The pint-sized fashionista sparkled in a gold jumpsuit and gladiator sandals before heading inside to perform “21st Century Girl” and “Whip My Hair” as her father Will Smith looked on.

Will.i.am was so 3008 in his futuristic red shades and Christian Louboutin studded shoes, opening the show with his group the Black Eyed Peas, who picked up the award for Favorite Music Group. Snoop Dogg arrived with his wife and daughter, getting slimed during his performance with boy band Big Time Rush. Justin Timberlake was honored with The Big Help Award in recognition of his work as a philanthropist and environmentalist.

What a difference a year makes. It was only last year at Nickelodeon’s Kids’ Choice Awards that Usher was introducing his protégé Justin Bieber to the world, and now the 16-year-old pop sensation is performing his top 10 hit “Baby” in front of millions at the 23rd annual event. J.B. took it all in with fellow teen star and Atlantic Records signee Diggy Simmons at UCLA’s Pauley Pavilion in Westwood, Calif., on Saturday (March 27).

It was a family affair as celebrities including Will Smith, Snoop Dogg, Jermaine Dupri, Chris Rock, and Swizz Beatz brought their sons and daughters to the slime fest. 18 photos below, plus watch Bieber perform “Baby.”

Chris Brown has withdrawn his name from the ballot at this year’s Nickelodeon Kids’ Choice Awards.

The embattled pop star was nominated for Favorite Male Singer and Favorite Song for “Kiss Kiss” at the 22nd annual show. A petition had circulated to take his name off the ballot, but Nickelodeon said yesterday he was still on. He has since withdrawn his name after being charged for allegedly beating Rihanna.

In a statement released Wednesday, a rep for Brown said:

“Chris very much appreciates the support of his fans and the honor they have paid him in the way of nominations for Favorite Male Singer and Favorite Song.

Unfortunately, the controversy surrounding the incident last month has shifted the focus from the music to whether he should be allowed to be among those nominated.

While Chris would like to speak to his fans directly about this and other issues, pending legal proceedings preclude his doing so at this time. Once the matter before him has been resolved, he intends to do so.”

Rihanna is nominated for Favorite Female Singer and Favorite Song for “Don’t Stop the Music.”

The Kids’ Choice Awards 2009 will air live from Los Angeles on March 28.

Janet Jackson was a presenter at Saturday’s Nickelodeon Kids’ Choice Awards 2008 at UCLA’s Pauley Pavilion in Westwood, CA.
