The singer-turned-actor stars in the big screen adaptation of the Andrew Lloyd Webber stage show alongside Taylor Swift, Idris Elba and Judi Dench, and early glimpses of the movie have been met with a largely negative response due to the combination of live action and animation, with many finding the mix awkward.
Speaking with Australian publication Confidential, Derulo confessed he was shocked by the fan reaction when the first trailer dropped in July, admitting: "I don't think I have ever seen such a polarising reaction from any other trailer ever".
Confessing the finished scenes look exactly the way he thought they would "from the jump", he explained the new film is everything he "hoped it would be because that is what I felt like was the magic of the stage play".
He continued: "It is unlike anything that you've ever seen before so everything that has been said about it being creepy or left and weird, it is all of that and more".
The musical movie features the "Talk Dirty" hitmaker as mischievous feline playboy, Rum Tum Tugger, with Derulo's fellow popstar Taylor Swift starring as Bombalurina.
On Friday, November 15, Swift released "Beautiful Ghosts" - her original song from the project. In the film it will be performed by Francesca Hayward who plays Victoria the White Cat. The "Lover" singer's version will play over the end credits.
"Cats" is released on 20 December.
