Wiz Khalifa took his frohawk haircut on the David Letterman show last night (11.04.11).

The 'Black and Yellow' rapper - whose album 'Rolling Papers' recently entered the Billboard 200 chart at number two - performed his latest track 'Roll Up' on the program, impressing the host, who called him a "popular new rap artist".

He's definitely not wrong.

Wiz tweeted a picture of his customary frohawk, but its days could be numbered as the rapper later wrote: "Blowin tha frohawk out since he got his own trendin topic n all (sic)."

His 'Black and Yellow' single - which was named after the colors of the Pittsburgh Steelers - peaked at number one on the Billboard 100 Hot chart.

Perhaps Wiz's success is down to how he gets each day off to the ideal start by having a smoke.

And earlier today he revealed further reason for Celebration, tweeting: "Finally wrapped both videos...smoke a victory doob wit me (sic)."
