Did Demi diss Ariana?

When Ariana Grande dropped out of an MLB All Star Game concert only to be quickly replaced by Demi Lovato, many assumed that the switch had to with Ariana's "I hate America" donut incident. More fuel was added to the audience, "How many of you guys are proud to be an American?" an apparent subtle jab at Ariana's bad behavior. Well, Demi is clearing the air once and for all. "No shade," she tweeted. "I ALWAYS ask that when I sing 'Made in the USA.' Can't y'all let a girl shine for one night?" Whew! we're glad there's no drama between these two talented ladies!
