The awards, which are determined by online voting, honor popular teens in film, television, music, comedy, sports, fashion, and the Web, which is new this year.

Presenters include Kellan Lutz, Chloe Grace Moretz, Cody Simpson, Hailee Steinfeld and Zendaya. Singer Jason Derulo will perform.

A recent water main break flooded the Teen Choice Awards' original venue at UCLA's Pauley Pavilion and the show was hastily moved across town to the Shrine Auditorium adjacent to the USC campus.

The 2014 Teen Choice Awards airs live on Fox from 8 p.m. to 10 p.m. EDT on Sunday.
