The duo popped into the famous house as part of the 'For Whom The Bell Tolls' task and told Jim how well he is doing and how proud they are of him.
Jim's wife also took the opportunity to reassure him that their house was not flooded during the recent heavy rain - and poked fun at one of his arguments with Luisa by bringing him some freshly ironed shirts.
The duo shared some news of loved ones who couldn't visit the house, and the visit was so emotional that Dappy shed a tear.
"You're famous on Twitter," Jim's daughter added. "You're hilarious. Everyone's loving your one liners - keep them coming, keep making everyone laugh."
She also suggested that he would win, while Jim's wife said: "Not long now. Not long now and you'll be back home with us."
When the pair had left the house, Luisa raved about Jim's "gorgeous" wife, while he went to hang up his shirts and have a moment alone on his bed.
