Swift, who reportedly split from Styles last month (Jan13) after a brief romance, is nominated for three trophies at the upcoming ceremony, including Favorite Song for her break-up hit We Are Never Ever Getting Back Together.
Ironically, the song puts her in direct competition with Styles, who is nominated in the same category with One Direction for their track What Makes You Beautiful.
The singer and the boyband will face competition from Psy's megahit Gangnam Style and Call Me Maybe by Carly Rae Jepsen.
A statement from Styles reads, "We are delighted with our nominations for the Kids' Choice Awards... Thank you as always to our incredible fans and supporters!"
Swift is also competing for Favorite Voice from an Animated Movie for The Lorax and Favorite Female Singer, while One Direction are also up for Favourite Musical Group alongside Bon Jovi, Maroon 5 and Big Time Rush.
In the Hollywood categories, the contenders for the Favorite Movie award are The Amazing Spider-Man, The Avengers, The Hunger Games, and Diary of a Wimpy Kid: Dog Days.
The Hunger Games star Jennifer Lawrence will do battle with The Avengers' Scarlett Johansson for the Favorite Movie Actress trophy alongside Vanessa Hudgens (Journey 2: Mysterious Island) and Kristen Stewart (The Twilight Saga: Breaking Dawn - Part 2).
Johnny Depp (Dark Shadows), Andrew Garfield (The Amazing Spider-Man), Zachary Gordon (Diary Of A Wimpy Kid: Dog Days) and Will Smith (Men in Black 3) are in the running for Favorite Movie Actor.
Nickelodeon's 26th Annual Kids' Choice Awards, hosted by actor Josh Duhamel, will take place at the University of Southern California's Galen Center in Los Angeles on 23 March (13).
