Travie McCoy - "Don't Pretend" (To Katy Perry)
Travie McCoy and Katy Perry were together before either one of their careers sky rocketed, so no one thought fame wouldn't affect them. But when Katy blew up faster than Travie, he turned to drugs to cope with the awkward transition. Katy knew that his image wouldn't help hers so she kicked him to the curb... via email. (Ouch!) But karma kicked back when Katy moved on to Russell Brand and got a divorce.
