Miley Cyrus leads the nominations for Nickelodeon's 2011 Kids' Choice Awards.
The 18-year-old singer and actress will compete for honors in three categories, Favorite TV Actress - which she will contest with Miranda Cosgrove, Selena Gomez and Victoria Justice - Favorite Singer, and Favorite Movie Actress.
In the musical category, the 'Party in the USA' hitmaker faces competition again from Selena Gomez, as well as Katy Perry and Taylor Swift, while Ashley Judd, Kristen Stewart and Emma Watson are also up for Favorite Movie Actress.
Elsewhere, in the film honors, 'The Karate Kid' is up for three awards, including Favorite Movie, Favorite Movie Actor for its star Jaden Smith and Favorite Butt-kicker for Jackie Chan.
'Toy Story 3' and 'Shrek Forever After' will go head-to-head in two categories, with both up for Favorite Animated Movie and 'Toy Story's Tim Allen and Tom Hanks competing with 'Shrek's Eddie Murphy and Cameron Diaz in the Favorite Voice from an Animated Movie group.
Cameron - who voices Princess Fiona - told People: "Well, as everyone knows, the kids know their stuff, so I'm always very flattered to be their choice for anything. After all these years, Fiona is very close to my heart and it's awesome to know that kids around the world love her as much as I do."
Other notable categories include the Favorite TV Actor, which sees brothers Joe and Nick Jonas compete against twins Dylan and Cole Sprouse for the prize.
