DUSTIN JOHNSON was victorious on and off the course as he celebrated his Ryder Cup win by kissing Paulina Gretzky, his fiancee.

The world No2 was the fifth overall player and fourth American to win all five matches in a single weekend.

DJ defeated Paul Casey with the win confirmed by Collin Morikawa minutes prior.

Paulina, his beautiful partner, was there in matching 'Johnson" sweater to congratulate him for the 18th green.

Gretzky, Gretzky's daughter, was enjoying the atmosphere with Team USA Wags.

Katherine Zhu was quick to embrace Morikawa after the win. Sophia Bertolami, Bryson DeChambeau’s girlfriend, also showed her love for the big-hitting star.

Only Rory McIlroy and Ian Poulter won their singles matches in Europe. The Americans beat Whistling Straits 19-9, with Daniel Berger winning the last point against Matt Fitzpatrick.

The USA team and its partners didn't waste any time in getting the party started. They enjoyed drinks at the end the 18th, just before the last singles matches ended.

Johnson, a veteran of the American Ryder Cup team at 37 years old, was clearly relaxed during the press conference.

Although he is usually quite bland behind the mic, a few beers and the excitement of winning got DJ in good spirits last night.

After lifting a microphone up Morikawa’s polo, the scion confessed to a 'bromance’ with The Open champ, whom he had partnered to win both his foursomes.

Johnson stated, "Yeah, we got bromance. It's okay.

"I didn't expect 5-0-0, that is for certain. But, I did not expect to play five matches.

"Obviously, we started off well and had some good relationships there with Collin [Schauffele]], so Captain just kept the wheels turning.

"I felt that the game was coming together. Ryder Cup is always an enjoyable week.

"It's so much more fun to go out and play like this golf, just because it's not something we do often - and it's certainly a lot more fun when it wins."

When asked if Morikawa and Tommy Fleetwood could recreate Francesco Molinari's 2018 bed-sharing celebration video, he refused to back down.

Two-time major champion laughed and said, "If you want to me to, absolutely." I ain't scared."

Johnson refused to swear when Johnson said he could out-party all the US players 'abso...lutely' despite his age. He then promised to get a tattoo on the backside of captain Steve Stricker - much like Thomas Bjorn did three years ago.

DJ said, "Strick, I'll make it happen if you do it." You all heard it.

"I'll do whatever you want to my a**cheek."

Tony Finau, Tony's teammate, quickly got in on the act and said: "DJ will probably need to ask Paulina."
