Still Blazin'! Wiz Khalifa throws caution to the wind and smokes his way down Hollywood Boulevard marijuana joint in hand

He sings about it and he has a business surrounding it, so Wiz Khalifa is not about to hide his smoking habit.

The 27-year-old rapper took to the streets of Hollywood on Monday night joint in hand.

While medical marijuana is legal in California, most people do not casual stroll down on the busiest streets in the world smoking it.

But the Black And Yellow rapper was not letting social convention stand in the way of his high as he headed to the Project Club for producer Mike Will Made It's birthday party.

While when most celebrities step out smoking a hand rolled cigarette there is a possibility it is tobacco, with Wiz he would almost be insulted if people thought that.

The rapper is far from shy about his fondness for marijuana, rapping about it often - especially in hit track Still Blazin' - and even sells his own rolling papers, which he appeared to be using on Monday night.

While he got the party started early, the musician headed out in his normal casual style wearing a Pittsburgh Pirates baseball jersey, a pair of black skinny leg jeans.

The rap star accessorised his look with Converse shoes and a Bathing Ape hat.

The heavily tattooed star headed to the party surrounded in an all-male entourage despite being back on the market for some time now.

Wiz split with wife Amber Rose in September amid reports of infidelity on both sides.

Amber denied she ever cheated on her husband but this month his new song For Everybody suggested otherwise, making comment about her raunchy antics on Instagram.

Wiz has also denied cheating on the model, who is the mother of his two-year-old son Sebastian.
