AUSTIN, Texas — In what is sure to be just one of many unscheduled celebrity appearances during South by Southwest this year, Justin Bieber gave a surprise performance at sausage and beer joint Banger's on Sunday night.
An awestruck María Núñez was among the attendees at the restaurant for the Sunday Funday event thrown by Bieber's manager Scooter Braun, capturing her own reaction in this selfie — with 20-year-old Bieber in the background:

"What the actual f*ck just happened," she later tweeted to another Twitter user a few hours before noticing her selfie was spreading quickly across the Internet.
Nothing's more iconic than finding out your face is being used as a reaction meme on tumblr #priceless

Bieber played a set, reportedly addressing Selena Gomez as "my baby" at one point before singing his hit song "As Long As You Love Me."
