If you were at the Lupe Fiasco concert Wednesday night in Austin at the Belmont, the Chicago rapper wasn't the only celebrity you might have caught a glimpse of.
According to Fiasco's Twitter, Bill Murray was in the building and if you weren't there you really missed out.
Fans also chimed in with their reactions.
And if it wasn't enough to have the Ghost Buster's and Lost in Translation star in the building, he also did a favor for the entire audience. He made the 'Kick Push' artist give two encores to which Fiasco was more than happy to oblige.
