I think Idol doesn't have a problem with giving promo slots to X factor contestants, especially with Demi performing next week. Alex and Sierra were even showed on camera when they were there.
Plus, they had no problem with contestants covering One Direction and Little Mix - but then again, those were contestants from the UK version which isn't really associated with American Idol.
Columbia is a damn mess. Like I'm done with them. Alex & Sierra tweeted yesterday that they had a bad day, and I'm pretty sure that has everything to do with Columbia being shady by promoting John Legend more that them
At this point I am 100% sure the lyric video is not coming today. The single is not coming for at least another month.
