Ryan Reynolds and Will Ferrell are putting their own spin on the “Grace Kelly” TikTok trend.

The pair have been filming their new Apple Original Films holiday musical “Spirited”, which is a modern musical rendition of Charles Dickens’ 1843 classic holiday story “A Christmas Carol”.

The flick was first announced back in September 2019, but was pushed back due to the ongoing coronavirus pandemic.

Despite pointing out it’s too early for the Christmas movie musical just yet, Reynolds shared a clip of him and Ferrell showing off their vocals.

The “Grace Kelly” TikTok trend sees social media users perform the different harmonies in Mika’s hit 2007 track. Reynolds began the track, only to be surprised when Ferrell turned up to sing the higher parts of the song.

He posted:
