Singer Wiz Khalifa - currently in Malta for the Isle of MTV show - lived up to his reputation when he posted a picture of himself at the Blue Lagoon with the caption "I smoked a joint in Blue Lagoon today".
It is not known if he faces police action.
Earlier this month, 26 people were arrested at the Earth Garden festival in Ta' Qali when they were found in possession of what was thought to be cannabis.
Wiz Khalifa has reportedly always been attached to weed. He even claimed that he is spending about $10,000 monthly to fund his drug habits.

Once asked by MTV if he thinks marijuana should be legalized, he had said: “Definitely, legalise it. Please, everybody needs it. The world would be a better place.”
Wiz’s biggest hit to date, the 2015 global smash See You Again, was the lead single from the Fast & Furious 7 soundtrack and hit the top spot on charts across 95 countries. His sixth studio album Khalifa was released last February.
He will be performing at the annual event on the Floriana granaries tomorrow.
