#20 – Bruno Mars
Bruno Mars can be proud of himself because he is now one of the most popular singers in the whole world and everyone sings along to his popular songs such as “Grenade” and “Treasure.”
However, Bruno wasn’t such a treasure all his life. In 2010, this talented singer was arrested for the possession of the illegal drug cocaine. If this would have happened during his fame, we think that Bruno would have lost his credibility.
