Great Britain's Jessica Gadirova won gold in the floor finals on the final day of the Gymnastics World Championships, in Liverpool.
Competing last, Gadirova scored 14.2 to beat Jordan Chiles, from the United States, who scored 13.833. Jade Carey (USA) and Rebeca Andrade (Brazil) shared the bronze with 13.733.
The final field included her twin sister, Jennifer, who finished seventh.
"When I focus on the dance, it takes my mind away from the crowd and the tumbles and the leaps, and it makes me feel alive," Gadirova said after her win.
"That's what I am. I love to perform and floor is one of my favorite pieces to do. It gives me such an amazing feeling."
It was the 18-year-olds third medal of the event, after winning silver in the team event and bronze in the all-around competition.
The win marks just the fifth time a British athlete has become a world champion in gymnastics.
The two-time European floor champion had struggled with injury prior to the finals, telling BBC Sport: "I'm just so relieved it was worth it, I pushed through the pain and it was worth it."
"I am so proud of myself to just keep fighting and try to focus on my own individual performance and I didn't listen to anyone else's scores."
Gadirova's victory meant Great Britiain finished on a record-breaking six medals from the World Championships.
