Louise and Dan took to Twitter to tell fans the former had unexpectedly won the trophy at the charity event.
Today, Louise told her 164,000 followers the pair had hugged for the first time to celebrate the news.
The mother-of-two shared a picture of her holding the trophy alongside the group with the caption: “Unreal.
“My team were fab, I just managed to hang on in with them with my borrowed shoes and clubs!”
One user then asked: “Did you get a congratulatory Hug from Dan or was it a brisk handshake?”
Louise replied: “We actually hugged! World first that too.”
Another fan asked the presenter if she had played golf before.
They wrote: “@louiseminchin did you say you have never golfed before? To settle a chat with my husband.”
Louise replied: “I have played before but many years ago!”
Earlier today, Louise also admitted Dan and others were shocked by her win.
The presenter shared a picture of herself and Dan in the studio with the caption: “Good morning, in very unexpected news I won a golf trophy, the Walker Cup, (not that one) to the shock of everyone including @mrdanwalker thanks to my fab team mates Dave, Dean and Chris.
“We were raising money for @SheffChildrens I will never let him forget this!!”
The host told fans she was nervous about taking part, but insisted the day was “brilliantly funny”.
She wrote: “I was very nervous about turning up to play in this, but what a brilliantly funny day despite the rain!
“Thanks to everyone involved.”
Television presenter Gethin Jones replied to Louise’s post writing: “Well done champ!”
She replied: “What an unexpected bonus and lovely to see you!”
