The hit mystery drama scored the most surfboard trophies of the night with six, including its fifth consecutive win for Choice TV: Drama, and individual acting prizes for Ashley Benson, Ian Harding, Janel Parrish and Sasha Pieterse. Benson won an additional honour for Choice TV: Chemistry with her onscreen love interest played by Tyler Blackburn.
Benson's pal and Spring Breakers co-star Gomez was also a big winner, but since she is currently on the road for her Revival Tour, the singer sent in a video message thanking fans for voting her Choice Female Artist, Choice Summer Music Star: Female, and Choice Instagrammer.
Receiving a special honour was Justin Timberlake, who was presented with the first-ever Decade Award by basketball icon Kobe Bryant. The pop star was given the accolade for "dominating the world of entertainment" over the past 10 years, and with the win, he made Teen Choice Awards history as the male star with the most victories with an impressive total of 23.
Meanwhile, other big winners included Daisy Ridley, who was named Choice Movie Breakout Star, Chloe Grace Moretz, a victor for Choice Movie Actress: Comedy for Neighbors 2: Sorority Rising, and Chris Evans, who won his first Teen Choice Award for Choice Movie Actor: Sci-Fi/Fantasy, while Captain America: Civil War also won Choice Movie: Sci-Fi/Fantasy.
Performances at the Los Angeles prizegiving, co-hosted by Victoria Justice and John Cena, came from the likes of Flo Rida, Charlie Puth, and Jason Derulo, but one of the highlights was Ne-Yo, singing a cover of Marvin Gaye's anthem What's Going On in tribute to those who have lost their lives due to gun violence in America.
