“Silicon Valley” star Kumail Nanjiani just revealed why tech billionaire Elon Musk wasn’t a fan of the hit HBO show.

During an appearance on the Aug. 10 episode of Mike Birbiglia’s “Working It Out” podcast, the Marvel actor recalled how the series received a lousy review from the Tesla titan when Nanjiani met him.

“He didn’t like the show,” the actor dished.

Apparently, Musk wasn’t amused by the series’ 2014 opener, which featured Kid Rock performing at a posh tech party while “seven nerdy dudes” stood by with no one “paying attention.”

“It’s such a funny opening,” Nanjiani told Birbiglia.
