British swimmer Fran Halsall grabbed silver in the 100m freestyle on day six of the World Championships in Rome.
Halsall, who got Britain's fifth medal of the meet, finished second behind Germany's Britta Steffen.
Steffen broke her own world record with a time of 52.07 seconds, Halsall did it in 52.87 seconds, while Australia's Libby Trickett was third in 52.87.
Halsall found it hard to contain herself: "I can't stop giggling - I can't believe it," she said.
And the other big news in the world of swimming is the fact that controversial new swim suits will be banned sooner than we originally thought.
The new suits are made of a material that helps swimmers move through the water, and lots of people think that's cheating.
A ban on them was set to come in to force in April or May.
But that was brought forward to January after Olympic legend Michael Phelps said he would stop competing until they were scrapped.
