BRYSON DECHAMBEAU was seen wearing his funny Brooks Koepka Tshirt, which is proof that their feud has ended.

After the historic victory of the USA, Europe beat the USA 19-9 in the Ryder Cup's largest margin of victory since 1967, the former rivals hugged each other for the cameras.

DeChambeau (28), wore a 'Step Brothers’-themed T-shirt, with Koepka and his faces photoshopped onto actors Will Ferrell & John C. Reilly at the Ryder Cup After-Party on Sunday.

Justin Thomas, a USA teammate, made the shirts as a joke and posted a close-up photo of one of the prank tops to his Instagram story.

Thomas, 28 years old, was believed to be the key to building America's team spirit. He also made DeChambeau and Koepka hug after their victory media session.

The 2017 PGA Championship winner laughed while singing Smash Mouth's 'Why Can't We Be Friends'. As the two embraced, it was officially the end of their feud.

Steve Stricker (54), the captain of the USA team, pulled the two players aside prior to the Ryder Cup and told them to forget their rivalry before they joined the team.

They clearly listened to the captain's instruction and were able to put aside their differences. This led to Europe's worst Ryder Cup defeat.

DeChambeau & Koepka started their feud in 2018. Koepka (31), criticised DeChambeau's slow style.

Koepka stated: "I don't get why it takes me so long to hit a golfball. It's not that difficult."

"It's always between 2 clubs, there is a miss short and miss long. It drives me crazy."

DeChambeau retorted by claiming that Koepka didn't have any abdominals. Koepka replied by posting a photo of his four Major trophies along with the caption: "You were correct @b_dechambeau. I am 2 short of 6 packs."

They seem to have finally put aside their rivalry for the good of the team, after what could've been an awkward situation for Steve Stricker.
