Selena Gomez to show, but no performance at Sunday D23 Conference

Did not announce it, but Selena Gomez and The Scene were set to perform at Sunday's D23 Convention currently going on at Anaheim Convention Center. A Radio Disney rep informed me today Gomez will be appearing, but not performing at the event. Awww.

Here current song, Falling Down, debuted last week at #51 on Billboard's 100 charts and dropped to #55 this week.
