It has been four years since Tom Holland graced the stage of Lip Sync Battle and delivered an iconic performance of Rihanna's song "Umbrella." His performance could have ended up being very different though!

Insider just did "An oral history of Tom Holland's sensational 'Lip Sync Battle' performance" article and revealed some secrets that we've never heard before.

The show's executive producer Casey Patterson revealed there was actually a back-up song prepared in case Rihanna's team didn't approve of the performance.

"We would clear song by song and have to go to each artist. We'd say we have Tom Holland coming on the show, and Rihanna would need to bless it. It's never a given," she said.

Costume designer Jeanie Cheek said, "We actually created two different sets of costumes for him and all of the dancers. Just in case "Umbrella" didn't go through, we had a backup performance."
