Strictly Come Dancing viewers never miss a trick when it comes to the couple's dances and the judges... judging.
But during Saturday's live final, a performance by Robbie Williams got fans talking as they spotted a major similarity.
The former Take That start was on the show to perform his song 'Time for Change' from his Christmas album.
Robbie, 46, pulled out all the stops as he took to the Strictly ballroom with a band in tow and rocking a very fesitve-looking, glitzy jacket.
However, it was the song that viewers felt was a 'rip off' of a rather famous track.
"Robbie, I love ya mate, but your new song sounds exactly like Iris by the Goo Goo Dolls #StrictlyFinal #Strictly," wrote one.
Another pondered: "This sounds a lot like Iris by The Goo Goo Dolls #strictly."
"Just can’t stop hearing Iris by The Goo Goo Dolls in this song #strictly," added a third.
A fourth commented: "Iris by Goo Goo Dolls but make it generically festive. #StrictlyFinal #strictly #RobbieWilliams."
"Sorry but I thought Robbie was singing Iris by the GooGoo Dolls?! #strictly #StrictlyFinal," another viewer tweeted.
