It's a full-circle Idol moment as Megan gets surprised mid-song by her hero Lauren Daigle, who was on Idol seasons 9 and 11 (in Vegas too)! Megan turned to exclusively Christian music after trying to play in seedy bars and feeling like she had to pretend to be someone else to get people to listen. Watch 'American Idol' SUNDAYS 8/7c on ABC and Stream on Hulu.
