Selena Gomez has a rebellious side too! Justin Bieber 's ex GF attempted to seem unaffected by his arrest this morning, but that might not be the case with a closer look. The seemingly sweet and innocent starlet stopped by an El Lay gas station to stock up on caffeine and a pack of Djarum clove cigarettes. She must be having a rough day! Hopefully she doesn't get hooked on the nasty, deadly habit… ..for her sake and her young, impressionable fans!
