You know you're not over your ex when...

...you tell the world how much you hate him, and you get your current boyfriend to dress up as him for Halloween.

Yes, the one and only, Miley Cyrus proclaimed her hatred towards ex-boyfriend, Nick Jonas, during one of her recent performances (see below), when she introduced her song "7 Things" by saying, "It's for all the girls, I guess guys out there too, that hate their, uh...ex-boyfriend." At the end, she added, "I still hate you."

Meanwhile, her 2o-year-old boyfriend, Justin Gaston, decided to dress up as Nick for Halloween (pictured above), while Miley's older sister's boyfriend dressed up as another one of the Jonas Brothers.

Just goes to show that Miley really is a bitch. Please, I know you're only 15, but if you're trying to make yourself look and seem older, then at least grow up and stop being so immature.
