Post Malone has a number one hit with 'Rockstar.'

But is he a rock star? He's got the hair. He likes the drugs and booze.

However, he came up a bit short when it comes to the ultimate rock star move: the guitar smash. Watch him try his best below:

Post does ultimately break the instrument. But it took him six tries, and there was a risk that he would bust a hole in the stage before he killed the guitar.

If you are catching Post on his current tour, expect him to try again.

help @Postmates I wanna order 100 guitars to smash on tour but it's only letting me order 10!
