Noted scientist John Mayer says Juan Pablo Galavis didn't look very happy on "The Bachelor" when he was with winner Nikki Ferrell.

What? Well ... OK, maybe it isn't the busiest news day.

E! News reported that not only does the singer watch the hit ABC series, he has the ability to analyze Galavis' facial expressions.

"Thinking about Juan Pablo led me back to this book on my shelf called, 'Unmasking The Face' (I like super dense esoterica.) The book refers to itself as a 'guide to recognizing emotions and facial expressions,'" the 36-year-old shared on his Instagram account on Wednesday.

He continued, "Turns out Juan Pablo was showing figure 28, contempt with some disgust, with a sadness brow featured in figure 60."

Yep. Slow news day.

In other exciting Juan Pablo Galavis news, the 32-year-old Venezuelan was spotted looking undisgusted Tuesday with Ferrell at an exhibit of Hebru Brantley's work presented by Dom Perignon at Toys for Boys in Miami, said E! News.

An eyewitness said they looked like "a very happy couple."

Whew!

Sources said the couple (wink, wink) arrived around 8:30 p.m. and stayed for about an hour, mingling with the owner of Toys for Boys, a gallery and event space and enjoying some beverages.

"They were very affectionate and walked in hand in hand, and he had his arm around her most of the night," a witness said. "They looked like a really fun and friendly couple and were really into each other."

If you're bored, you also can check out Galavis' musical video tribute to his maybe girlfriend Ferrell, which he posted on YouTube on Tuesday.

And in even MORE exciting Juan Pablo Galavis news, he has a friend in former bachelorette Jillian Harris, who competed on Jason Mesnick's season of "The Bachelor" in 2009 and then went on to become the fifth Bachelorette later the same year.

In a blog posted to her official website March 12, Harris slammed Galavis' haters and said she was "disappointed" in how host Chris Harrison and some fellow Bachelor alum treated Juan Pablo.

"Do I think Juan Pablo was a great Bachelor? No, not really," she wrote. "I think the role is more fit for guys who are in touch with their feelings ... The Bachelor is usually someone who is sensitive, a good listener, a people pleaser & a hopeless romantic. The truth is, Juan wasn't really that guy. That does not make him a BAD guy ... maybe just not fit for a show juggling 25 women."

That must have been rough.

And because you care, know that Harris (who is no longer with her Bachelor fiance, Ed Swiderski) also wrote that she didn't agree with everything Galavis said and did, but that he may have been "coached" or "tweaked" by producers along the way. Her biggest issue, though, "is the way the franchise dealt with all (the drama)."

"The franchise is a part of me," she wrote. "I call it my family -- and when you care about something a lot you always want them to take the high road -- I don't think that happened this time."
