The first person that popped up in my head was PC.
She's a top actress who was in the news for all the wrong reasons. She has a big summer coming up with her album and Barfee.
And I didn't know her dad was in the last stage of cancer. That's horrible. Seeing a close family member, especially a parent, go through that is enough to push anyone to drinking/smoking as a way to relieve the stress and to deal with it. I've seen my dad take to smoking when my grandfather was in his last stages of cancer so I can relate..
