Rapper Wiz Khalifa is trying to come up with a new tattoo design to cover up a botched inking on his hand.

The hip-hop star has covered his body with skin art but there's one drawing he really regrets.

He tells America's Sister 2 Sister magazine, "I've got to cover it up, because the guy who did it, he tried to do it in colour and it didn't really come out how it was supposed to. It was, like, a plant that grew a face and then it turned into some other stuff... He drew it. It was a really good drawing, but the way he did it didn't come out right."
