We all know that Nole is a great showman and that he loves to sing. He recorded a song with Ivo Karlovic and several days ago he performed with Bryan brothers during the Arthur Ashe Kids' Day.

But Nole doesn't sing just for public, he loves to sing at home too! Together with Bogdan Obradovic (Serbia's Davis Cup captain) he had some great time at the house where he stays during the US Open. His girlfriend Jelena was there too, just watching all that!

Bogdan had an acoustic guitar and two of them sang Serbian folk song "Crne kose" (Black hair)! Nole wrote on his website:

"The video below is showing that we can’t live without folk music, even here in far away America. :-) Boca proved to be an excellent musician with an acoustic guitar and I, as a real "kafana-lover". We won’t speak about our vocal abilities, you will hear it. But more important than voice is the fun that my friends and I had! :-) That’s also something we do between training sessions."

And here is Nole's performance with Bryan brothers!
