Who knew Brad Pitt is such a huge Game of Thrones fan?! Or maybe he's a big fan of Emilia Clarke ...

The sexy actor ponied up a whopping $120,000 to watch an episode of GOT with Emilia at Sean Penn's HRO Gala: A Gala Dinner to Benefit J/P Haitian Relief Organization Saturday night in LA during a charity auction.

"During the first auction, Brad was on his phone. When the auction announced Emilia Clarke, they called her out in the crowd and Brad literally turned his whole neck to find and look at her and enthusiastically clap," a source tells Us Weekly.

Brad eventually gave up when another guest bid $160,000 for the experience and others in the crowd like Leonardo DiCaprio and Amazon chief Jeff Bezos watched as Brad laughed when he was called out for not continuing to bid.

So does the 54-year-old actor have a thing for the 31-year-old Clarke? Apparently not so much so that he's willing to pay more than $120K to hang out with her!
