Ryan Reynolds and Will Ferrell are proving they have some serious range.

On Monday, Reynolds, 44, posted a funny video on social media showing off his voice for a recent TikTok challenge. The Deadpool actor was singing Mika's 2009 hit song "Grace Kelly," repeating the chorus as he harmonized with himself each time.

Ferrell, 54, then appeared in the clip belting in a hilarious falsetto as Reynolds looked confused before joining back in.

Many followers joked in the comments asking the actors to release more duets and drop an album together. The singing challenge even got the approval of Octavia Spencer, Jeremy Renner, and Jordin Sparks.

Over the summer, Reynolds tweeted about his excitement for the AppleTV+ project as they kicked off filming. However, the movie does not have a release date yet.

"Day 1 shooting with one of my comedy idols, Will Ferrell," he wrote in July, going on to joke, "You'd barely notice this was an @Apple movie! Also iOS 14.6 will begin installing in 7 seconds … "

Both stars are veterans to holiday films. Reynolds starred in the 2005 Christmas romantic comedy Just Friends (which he recently recreated a scene from on TikTok!), while Ferrell was the titular character in the 2003 classic Elf.

Reynolds also helped the Hallmark Channel usher in the Christmas season early this year, insisting in a PEOPLE-exclusive clip that he "needs" the holiday movie season. In the hilarious footage, the actor said that the Hallmark films are like being "in a little snow globe" as he also promoted his latest movie, Free Guy.
