These multi-millionaire rappers, eh? More money than sense, sometimes.

That's certainly true of rapper Wiz Khalifa, who managed to anger a lot of people on his recent trip to Colombia.

After playing a gig in Medellín - the city known for spawning tyrannical drug lord Pablo Escobar - last week, he posted a picture of himself at Escobar's grave. The picture - now deleted - showed the gravestone with flowers and a joint, but not everybody was happy about his 'tribute', particularly the mayor of Medelln Federico Gutierrez.

As BBC report, Gutierrez called Khalifa a 'scoundrel' and said that he should have laid flowers at the graves of Escobar's victims, and should apologise for 'advocating crime'. "It shows that this guy has never had to suffer from the violence inflicted by these drug traffickers," he said.

Khalifa later posted another picture to Instagram (below) claiming that he 'didn't mean to offend anyone'.

Escobar and his cartel are reponsible for the deaths of an estimated 4,000 people.
