The final movie in the series, 'Harry Potter and the Deathly Hallows: Part 2' won the Choice Summer Movie accolade, while Daniel Radcliffe, who plays the titular character, picked up the Choice Summer Movie Star Male gong and his co-star Emma Watson, who plays Hermione Granger, won the female equivalent at the ceremony at the Gibson Amphitheatre, Los Angeles.
Taylor Swift was the biggest single winner on the night, taking home six prizes including Choice Music Female Artist, Country Music Female Country Artist, Choice Red Carpet Fashion Icon Female and Choice Music Country Single for her hit 'Mean'.
Accepting her Ultimate Teen Choice surfboard onstage, the 21-year-old singer joked: "It's been a long time since I was a teenager, like two years."
Selena Gomez nabbed five surfboard statuettes, including Choice TV Actress Comedy for her role as Alex Russo in the 'Wizards of Waverly Place' and Choice Music Love Song for 'Love You Like a Love Song' - beating her boyfriend Justin Bieber who achieved four wins.
The 17-year-old singer appeared on stage alongside his friend Sean Kingston, who was making his first live televised appearance since recovering from a jet-ski accident that left him needing two bouts of heart surgery and incapacitated with a broken jaw and shattered wrists.
Other multiple award winners included 'Glee', 'The Vampire Diaries' and 'The Twilight Saga: Eclipse', which picked up a hat-trick of gongs including Choice Movie Actor Sci-Fi/Fantasy for Taylor Lautner's portrayal of Jacob Black.
