A lot of people have been curious as to why Trace Cyrus bashed Ashley Tisdale, seemingly out of the blue, claiming that she had been spreading rumors about him. Well we were cruising some online message boards and found a theory that is quite interesting and very plausible. But remember, it's only a theory. Nothing is confirmed.
Anyways, it would appear as though Trace went on a few dates with Brenda Song, one of Ashley's close friends. Ashley, who is friends with Miley Cyrus and therefore likely knows Trace by association, may have warned Brenda about the tattooed heartbreaker.
Remember, this is all just a theory! Nothing's confirmed as of yet.
P.S. Why is Trace able to get so many beautiful girls? We have no idea. We don't see his appeal physically or emotionally.
