The singer was appearing on The Hot Hits Live on Monday when host Maude Garrett handed her an iPhone so she could watch a video message from a girl called Georgie, who declared her devotion to her music idol.
After watching the moving video, Gomez welled up, asking Garrett: "Why would you do that?"
The teary star then thanked the presenter for showing her footage from fans rather than quizzing her about her romantic life, saying: "I do know that every time I sit down to do interviews, it's usually based on who I'm dating, what I'm wearing, what's my favourite colour or favourite song.
"And when I find those people that genuinely appreciate me for me, it keeps me going. Georgie, you're the reason I do what I do. Thank you."
