Ryan Reynolds is promoting his new movie, “Free Guy” which features Mariah Carey’s hit, “Fantasy.” The actor took to TikTok for a lip-sync session of the song and it didn’t go unnoticed by the 52 year old diva. Mariah, who has seen “Free Guy” nine times, decided to get in on the fun with her own TikTok as she did a side-by-side duet with Reynolds. Carey lip-synced the song and then gave her reaction to Reynold’s “performance” of “Fantasy.” Mariah captioned her TikTok video,“#duet with vancityreynolds That wasn’t part of the plan!”
