One Direction scoop eight Teen Choice awards
Boy band One Direction have landed eight Teen Choice awards, bringing their "lifetime" total to 23.
The band, currently on tour, accepted the awards in a taped video shown at the Los Angeles ceremony.
The 17th Teen Choice Awards threw its full support behind the hit series Empire, honoured late Furious 7 star Paul Walker and paid homage to a respected elder - Britney Spears.
The two-hour teen celebration, broadcast live, kicked off with a victory lap for the weekend box-office hit Straight Outta Compton.
Ice Cube and the young stars of the NWA biopic, which earned an estimated 56.1 million dollars (£36m) over the weekend, welcomed the young crowd to Los Angeles' Galen Centre.
Christopher "Ludacris" Bridges, the rapper and Furious 7 co-star, was one of three hosts, alongside Jane The Virgin star Gina Rodriguez and actor Josh Peck.
Bridges' film, one of year's biggest big-screen hits, was one of the night's top winners, winning best action movie and best actor in an action-adventure for the late Paul Walker.
"Paul Walker is here in spirit with us," said Vin Diesel, a star in the street racing franchise. He applauded a "special, special" teen in the crowd: Walker's daughter Meadow.
The Teen Choice Awards spread awards across movies, music, TV, fashion, sports and digital media, celebrating the favourites - from Channing Tatum to Wiz Khalifa to Stephen Curry - of one of media's most powerful demographics.
As a pop star, Spears was a regular at the Teen Choice Awards, collecting its trademark trophies - surfboards - many times over the years, including its version of a lifetime achievement award in 2009.
This year Spears, her blonde hair partially dyed blue and purple, was honoured for being a style icon. She dedicated the award to her sons, Sean Preston and Jayden James, and niece Lexie, who were in the audience.
The hip-hop drama Empire won breakout TV show and provided one of the show's most memorable moments. While Jussie Smollett and Yazz performed You're So Beautiful, a song from the series, the show's Gabourey Sidibe made a surprise cameo, exuberantly dancing among the back-up dancers.
Ellen DeGeneres won for best comedian. Adding a Teen Choice Award to her People's Choice Award, DeGeneres requested awards from other age groups - the elderly and babies.
Several awards went to The Hunger Games: Mockingjay, Part 1, including best actor in a sci-fi or fantasy for Josh Hutcherson. He reflected on the end of the franchise, with this autumn's Mockingjay, Part 2, like a coming graduation.
"Hunger Games has been a huge part of my life for almost five years now. It's coming to an end and it's really sad," said Hutcherson. "So if we want to cry together, we can do that because it breaks my heart."
