The Showbears impressed the judges on Saturday night with a glittery performance of It's Raining Men, which saw David join them on stage.
He joked with the guys: "Look Simon, it's a new One Direction".
However some of the more fanatical 1D fans - and there are quite a few of them! - took the quip the wrong way.
The Showbears explained this week: "Some of the diehard One Direction fans really don't like us. After we were tagged the new One Direction they were branding us fat guys.
"But listen girls, this is what the boys will look like in 30 years' time! They had better get used to it. We are them."
Speaking to DigitalSpy, the group also revealed that their sparkling costumes put style ahead of comfort.
"They itch! They were made for a three minute routine and they are not lined. They are our version of Ginger Spice's Union Jack dress," the group added. "We are mildly grated by the time we remove them."
