Alicia Key's voice appears to have been smoothed out in Super Bowl

Fans are speculating that Alicia Keys' voice was seemingly polished after the version the NFL and Apple Music put out on YouTube.

During the live version of the Super Bowl LVIII Halftime Show, Alicia's voice appeared to crack during her first note of her song If I Ain't Got You before she sang the rest perfectly.

In the YouTube updated version, there is no crack in the first note and it appears completely smooth, causing fans to guess that it was edited out.

During Usher's headlining Super Bowl LVIII halftime appearance, he brought out Alicia for a surprise appearance.

She started off by singing If I Ain't Got You and the first note she sang her voice seemingly cracked.

After the misstep, Alicia, who was also playing the piano, sang the rest of the song perfectly.

She then started singing her duet with Usher - a song called My Boo.

Usher's incredible halftime show featured a medley of all his hits - in addition to several surprise appearances, with Alicia being one of them.

He also had H.E.R. as a guest appearance and also Lil Jon and Ludacris.

The YouTube uploaded version of Usher's halftime show has over seven millions so far, and is listed as number five in trending.
