On Sunday, Oct. 9, the U.K. held their BBC Radio 1 Teen Awards. In this gallery from the event, fans can see pictures of Joe Jonas, Jason Derulo, Cher Lloyd and Pixie Lott as they arrived and performed at the awards show.

Joe Jonas hit the red carpet looking cool and casual, as usual. The 'Just in Love' singer wore jeans, a T-shirt, and a navy blue and yellow letterman jacket. He later took the stage with some backup dancers to entertain the crowd gathered at the Wembley Arena in London with a live rendition of his song 'See No More.'  Jason Derulo also showed up for the awards show, wearing a brown leather jacket and jeans on the red carpet. He also performed at the show, singing and dancing along to his hit single 'Don't Wanna Go Home' -- Derulo even showed off some of his breakdancing skills!

Native Brit and pop hitmaker Cher Lloyd also posed for pictures on the red carpet before she performed at the BBC Radio 1 Teen Awards. The 18-year-old cutie wore a black and white polka jumpsuit pre-performance, and later changed into a midriff T-shirt and high-waisted patterned pants for her medley performance of 'Superhero' and 'Swagger Jagger.' U.K. cutie Pixie Lott also took the stage as the headlining act for the evening. Lott presented an award and performed tracks like 'All About Tonight' and 'Mama Do' while sporting a sassy outfit consisting of a black sparkly dress and leather cat ears.
