Beth Tweddle claimed Britain's first ever gold medal at gymnastics' World Championships after winning the uneven bars event in Aarhus, Denmark.
Tweddle won bronze in the event last year
The 21-year-old beat defending champion Anastasia Liukin into second place, with newly-crowned world all-around champion Vanessa Ferrari in third.
Tweddle scored 16.200 points, with Liukin scoring 16.050 and Ferrari achieving 15.775.
Gold is an improvement on the bronze she won in last year's championships.
The 21-year-old is the current European champion in the bars and finished eighth in Thursday's all-around final.
But after falling from the bars on Thursday, she recovered to put in her best performance of the week in the final.
"I knew that I could do the routine, it was just whether I could pull it out for that moment," she told BBC Radio Five Live.
"I went into the gym on Friday morning and did exactly the same routine as I would do that night.
"I went through first time and that brought my confidence back up again, and my coach knew that from then on she just had to keep me calm and let me get on with it.
The Liverpudian added: "All my hard work has finally paid off and I'm absolutely ecstatic.
"A lot of people told me it would come, but I didn't think it ever actually would. It hasn't sunk in yet.
"I've had the bronze medal at the last two world championships and to come out today after the fall yesterday and get through it is an achievement."
An ankle injury meant Liukin, the defending champion, could only take part in the bars competition but Tweddle paid tribute to her rival.
"I didn't know if I'd win because I hadn't seen Liukin's routine, but I've seen her in training and she was pretty spectacular," she said.
China continued their dominance with three more golds to bring their total to six.
Cheng Fei successfully defended her women's vault title, Chen Yibing beat twice former world champion Jordan Jovtchev of Bulgaria to win the men's rings title while Xiao Qin took gold in the pommel horse.
Elsewhere, the 2002 world champion Marian Dragulescu won gold in the men's floor event to give Romania their first gold of this year's championship.
Dragulescu, the 2004 Olympic silver medallist, beat defending champion Diego Hypolito of Brazil with Olympic champion Kyle Shewfelt of Canada taking bronze.
