The 22-year-old, whose latest single “The Heart Wants What It Wants” is rumoured to be about her on-and-off boyfriend Justin Bieber, appeared to be teary-eyed as she performed it live for the first time here at the AMAs Sunday, reports mirror.co.uk.
Gomez looked emotional towards the end of the song and even looked down to the ground, perhaps to avoid the cameras catching her mid-sob.
Her performance moved Swift, who appeared to be concerned for her emotional friend as the camera panned to her following Gomez’s moving performance.
In a prelude in the opening moments of the song, a tearful Gomez said: “When I was on stage and I was thinking of… I felt like I know… I know him, though, and I know his heart and I know what he wouldn’t do to hurt me.”
