The Office actor and the movie star were spotted getting all kinds of bromanctical Sunday night as a very exclusive post-Emmy party.
A spy tells us that after a few drinks Theroux and Krasinski bonded by "jumping up and down singing the end of Call Me Maybe" in front of everyone! LOLz!
Our on-looker goes on to say:
"Justin was having a blast. After he had his Call Me Maybe dance party, he hopped behind the deejay booth with Samantha Ronson and she gave him a tutorial!"
AH! It's just like Zoolander!
Hopefully he paid Sam back by showing her some basic breakdancefighting moves! Ha!
In the end it sounds like everyone had a BLAST!
We wouldn't be surprised to hear more about the budding Therinski's bromance!
