Watch Tyler Posey Surprise Fans Onstage For An Impromptu Performance With State Champs

Going on stage with State Champs? NBD.

Tyler Posey + State Champs = our fave bromance.

The "Teen Wolf" star hopped on stage with pop punk band State Champs -- which happens to be one of his all-time faves -- to perform "Elevated" on Tuesday (Nov. 3) at their L.A. concert.

If you follow Tyler on Twitter, you know his love for State Champs is deep. Back in February he confessed: "I had a dream i hung out with @State_Champs haha I feel like such a fan girl."

Going on stage with the band wasn't Tyler's first State Champs hang, though. During an interview in July, Ty revealed that he fell in love with them, started tweeting them, and then hung out with them -- casual. You may have spotted him in the music video for their song "Secrets" or seen the hilar Vine of the SC guys busting him about "Teen Wolf."

Tyler has been practicing for his on-stage moment for a long time. He posted an acoustic cover of State Champs' "Simple Existence" on his YouTube channel in 2014:

State Champs says Ty "killed it" -- so hmm, future collab maybe?! That would be rad.
