Looks like Ariana Grande has one more problem than she bargained for.
"The Big Bang Theory" star Mayim Bialik published a blog post on Kveller.com titled, "The Problem With That Giant Billboard Of Ariana Grande," to outline her distaste for the 21-year-old's sexualized album advertisements.
"Why is she in her underwear on this billboard though? And if she has a talent (is she a singer?), then why does she have to sell herself in lingerie?" the mother of two said.
But, Mayim isn't the first celeb to totally bash a pop singer! Check out the gallery below to see six other stars who have thrown some serious shade at a performer.
