Juan Pablo Galavis has drawn so much negative attention that even John Mayer is weighing in with his two cents! (Who knew he was a secret 'Bachelor' fan?) Mayer took to Instagram yesterday, March 12, to share with fans his complete facial analysis of Galavis, who has been labeled "Worst Bachelor Ever" by fans and celebrities alike.

"Thinking about Juan Pablo led me back to this book on my shelf called 'Unmasking The Face.' (I like super dense esoterica)," Mayer captioned the shot he took of the textbook, which features two deeply unhappy-looking faces. "The book refers to itself as a 'guide to recognizing emotions and facial expressions.'"

"Turns out Juan Pablo was showing figure 28, contempt with some disgust, with a sadness brow featured in figure 60 (not pictured)," the singer theorized. According to the book, Figure 28 depicts "the elements of disgust and surprise."

Chalk up Mayer as yet another Galavis hater -- something the 'Bachelor' star has seen a lot of recently.

“It’s hard because [viewers] saw a character on TV,” Galavis recently revealed. “A lot of things about me were not shown. I’m not a bad guy. People who know me, know who I am.”
