Canada's Justine Dufour-Lapointe tasted International Ski Federation (FIS) Moguls World Cup victory in Deer Valley as Perrine Laffont's perfect season ended. 

The Sochi 2014 Olympic champion defeated American Hannah Soar in the big final of the dual moguls event at the famous freestyle venue.

France's Laffont had won all six of the World Cups held this season before today, including the solo moguls competition in Deer Valley in Utah on Thursday (February 6).

However, he reigning Olympic gold medallist and dual moguls world champion was knocked out in the last 16 by American Tess Johnson to leave the way clear for Dufour-Lapointe.

All three of the other semi-finalists were American but the 25-year-old prevented a home victory as she opened up a lead over Soar before the first jump.

"I think today I just stopped watching other skiers and got back to focusing on what I can do better," said Dufour-Lapointe, who won the moguls world title in 2015.

"Every step of the way I was just focusing on 'okay, what's next'. 

"Those girls were going fast, and I knew this year that the speed had to be back, and I'm just so happy that I made it happen here in Deer Valley at this dual moguls event. 

"This is the most challenging course ever and to do it here just proved to me that I still have it."

Jaelin Kauf won an all-American small final against Johnson to secure bronze.

Laffont, who is hoping to win the World Cup moguls title for the third straight year, still has a commanding lead in the standings with 636 points.

Dufour-Lapointe has 389 in second and Australia's Jakara Anthony is third on 344.

In the men's event, Canada's all-conquering Mikaël Kingsbury returned to the top of the podium after finishing second to Japan's Ikuma Horishima in the solo event in Deer Valley.

The Olympic champion and four-time world gold medallist claimed his 61st World Cup victory by beating France's Benjamin Cavet in the big final.

"I had a good training yesterday and I was very satisfied with my skiing in the singles competition, so I wasn't worried," Kingsbury said.

"But I was definitely hungry and motivated today. 

"I think one of the things that made the difference is I was pushing really hard to the top air, making the other guys feel that they had to chase me through the first few moguls. 

"I think the pace I was setting was very high, and I knew anytime somebody was passing me they were probably going too fast. 

"It's a great feeling for me, win number 61. 

"After the Olympics this is the best feeling ever, winning at Deer Valley, I'm super happy." 

Kingsbury has now won five World Cup events this season as he bids to win the overall World Cup titles for both moguls and freestyle for the ninth season in a row.

He has finished second behind Horishima at the only two events he has not won.

In this season's moguls standings he now has 660 points, with his Japanese rival on 515.

Cavet is third on 386.

The World Cup season will resume in Tazawako in Japan on February 22 and 23.
