We are humans, sure, and we take addictions to anything that gives us pleasure. We are known to have addictions even to pain. Then there is all the odd stuff people are attracted and addicted to.
But the most debated of all the addictions is, yours pleasurely, $ex. $ex addiction is, often not considered an addiction, while the brain mapping studies and various other psychological observations have categorised it as an addiction, or at least the signs that the patients exhibit are same as other addictions.
And just like us, celebrities, whom we look up to, are also humans and many have been fighting their own battles against $ex addiction.
