Fact-check
An investigation by the Rumor Scanner team found that the video claiming to show Ronaldo singing a ghazal is not genuine, but was created through digital editing technology.
At the beginning of the investigation, a reverse image search of a keyframe led to a video titled “The FULL Cristiano Ronaldo Interview With Piers Morgan | Parts 1 and 2”, published on November 19, 2022, on the YouTube channel Piers Morgan Uncensored (Video link).

According to the video’s description, this 90-minute, multi-award-winning interview features footballer Cristiano Ronaldo speaking with Piers Morgan about a wide range of topics—from disrespect by Erik ten Hag to the Glazers. Ronaldo also criticizes the work ethic of young players and hits back at former teammates Wayne Rooney and Gary Neville, who criticized the Portuguese footballer’s behavior and footballing skills during his time at Manchester United.
Upon reviewing the video, it was observed that Ronaldo’s attire and surroundings in the interview video match exactly with those in the viral video. However, the audio of the viral video does not match the audio from the original interview.
In other words, the viral video was created by digitally editing a clip from Ronaldo’s interview session and overlaying it with a different audio track.
Therefore, the video circulated claiming Cristiano Ronaldo sang a ghazal is edited.
