Sprint superstar Dina Asher-Smith stormed to victory in the women's 200 metres at the World Athletics Championships in Doha.
It means she's now the first British woman to win a global gold medal in a sprint event at a major championships!
Not only that, but Dina broke the 200m British record to win the race in 21.88 seconds, breaking the previous record she set in Berlin last year.
It's after she had already won a silver medal in the 100m - and she could still take one more medal home with her as she competes in the 4x100m relay heats on Friday 4 October.
Dina told BBC Sport she had been dreaming of winning gold for years.
"I woke up today thinking, 'This is it. This is the moment you did all your work for'. The tiredness disappeared," she said after the race.
"The Olympics is less than a year away, we have already been thinking about it. I don't think there's any time we're not thinking about the Olympics." she added.
Her British team-mate and fellow sprinter Adam Gemili tweeted how proud he was of his friend, who he called a "little egg!"
