16-year-old star swimmer Ellie Simmonds has broken another world record!
She swam 200 metres in 3 minutes 8.98 seconds, beating the previous world record - which Ellie set herself - by a quarter of a second.
It grabbed her a gold medal at the European Championships in Germany's capital city, Berlin.
Ellie said: "It was quite hard, but I'm really happy - a new world record, I couldn't ask for more really."
It was great race for Britain, as teammate Natalie Jones got the silver medal too.
