Astrophysicist Neil deGrasse Tyson Has a Secret TMZ Addiction?!

Let’s just say Rach was *very* starstruck—no pun intended—when she met astrophysicist (and, in our humble opinion, national treasure) Neil deGrasse Tyson.

Of course, she had to find out what surprising, "un-genius" behavior he gets up to. As it turns out, even though Rach calls him “the smartest person in the room,” he loves some easy-watching TV. And we mean, really easy-watching.

The host of “Cosmos,” author of new book “Accessory to War,” and self-professed “card-carrying nerd” tells us, “Try as I might, I can’t channel surf past [comedy show] Tosh.0. It’s just stupid, crazy, and I want to get past it and my thumb is shaking and I can’t.” ?

He also tells us that he can’t resist a little TMZ -- and Rach couldn’t believe it!

“You can’t hit me with my own book!” Neil jokes. 

So, how did he get hooked on TMZ?

Well, he revealed something to us about his celeb status: the tabloid website's paparazzi started finding him at Los Angeles International Airport, and though he resisted at first, he soon realized that they’d be asking him science questions.

“So then I thought,” Neil admits, “this is the only way science will ever get on TMZ.” (Good point, Neil).

As of now, he’s been on there a whopping eight times.

As if we weren't already impressed enough by him, Neil also showed us a pretty cool 3D food printer that spit out Rachael’s logo—in CHOCOLATE—right before our eyes.

"Everybody’s got a little bit of geek in them” he says, “and my job is to tickle it, reveal it, have it rise back up.”
