Dirk Nowitzki Plays the Tambourine at Avett Brothers Concert (Photo)

Yes, that's Dallas Mavericks' star Dirk Nowitzki rocking an Avett Brothers shirt. Dirk might be more of a hipster than we ever thought.

Nowitzki made a cameo at the Avett Brothers concert yesterday and it was a hit to the audience.

Avett Brothers member Joe Kwon tweeted this about Dirk being there:

Cameo of the year goes to @swish41 for joining us on tambourine on Sally's Lover!

The Mavericks forward was playing the tambourine for the band.

Here's a photo a fan took of Nowitzki rocking the tambourine for the Avett Brothers:

If you go to an Avett Brothers concert soon, don't be surprised to see Dirk being there.
