Selena Gomez's Kiss Cam smooch with Justin Bieber was "the most humiliating thing that's ever happened" to her.

The actress and her boyfriend were watching the Los Angeles Lakers play basketball on last Monday night when they appeared on the court's Kiss Cam - which zooms in on couples to make them lock lips - and although they complied, Selena was enormously embarrassed. "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. It was so weird. I mean you have to kiss, right?" she told Ryan Seacrest on his radio show.
