Australia's Jessica Fox added C1 gold to her K1 title from yesterday at the International Canoe Federation Canoe Slalom World Championships in Rio de Janeiro, to complete a perfect season in C1 events.
Fox has now completed the K1 and C1 World Championship double twice after doing the same at Deep Creek Lake in the United States in 2014.
The Australian has also secured a fourth world title in the C1 with yesterday's K1 win making her the most successful individual canoeist in the history of the sport, advancing the mark set by her father, Richard.
She has now made more history by overtaking her mother Myriam Jersusalmi's record of world titles by a female paddler.
Fox's C1 gold takes her total world titles across all disciplines, including teams, to eight, which makes her the most successful female canoe slalom paddler of all time.
"It's been the perfect season, the perfect World Championships, I'm absolutely thrilled," Fox said after her display at the Rio 2016 Olympic course.
"Yesterday was really hard because I couldn't appreciate what I had achieved because I had the C1 semis in the afternoon.
"But now all the emotion is there, it's amazing to share it with everyone that's here - my team, my family - I can't wait to get home and celebrate.
"Growing up with two parents who were very successful in the sport was always pretty daunting, and I never thought I would be able to beat dad's record of five titles, or achieve what mum achieved.
"To beat them is very cool, very special, but it's as much their achievement as mine."
Fox dominated the event, posting a clean run of 109.07sec, almost five seconds faster than Great Britain's defending champion Mallory Franklin.
Franklin took the silver in 113.85 with Tereza Fiserova of the Czech Republic in bronze in 116.74.
In the men's K1 final, Hannes Aigner won his first world title and Germany's first K1 gold since 2005.
Aigner posted a clean run of 89.69 to take the gold over 2015 world champion and Czech paddler Jiri Prskavec.
"It was pretty hard for me to make this run, I had a lot of finals and didn't make a good performance," Aigner said.
"This was the first time for me to make a pretty good run in an important final.
"I risked everything, I didn't want to finish in fourth place, so it all worked out.
"Now this is my best season ever.
"We have a long tradition in K1 men in Germany, we have many titles, but the last title was a long time ago, so I'm happy to continue this series of success for Germany."
Prskavec’s time of 90.65 was enough to secure silver with Russia's Pavel Eigel finishing third in 92.17.
Eigel made history by winning Russia’s first World Championship medal.
