The 19-year-old put on a public display of affection with JB at the LA Lakers game on Monday night, where couples are encouraged to lock lips whenever the Kiss Cam zooms in.
Speaking to Ryan Seacrest on his KIIS FM radio show, Selena explained: "It's the most humiliating thing that's ever happened to me, probably.
"They were showing these little elderly couples and it was so cute. Then all of a sudden we're both looking up and we come on the screen and it's like... It was so awkward."
The teen couple duly obliged. Gomez added: "It was so weird. I mean you have to kiss, right?"
Yesterday Selena revealed that Justin's upcoming duet with Taylor Swift is 'beautiful'.
