Oh, Selena. Used to be so innocent. So wholesome. Now she's channeling her inner sexy independent woman side, and dropping everything related to her old Disney persona -- INCLUDING HER PARENTS!

Since day one, she's been managed by her Mamadukes and stepfather. Turns out, she straight up dropped them. Best part? THEY DIDN'T KNOW UNTIL THEY SAW THE STORY ON TMZ!

Selena said she's outgrown them and wants bigger management...which just makes her sound like SUCH an egotistical little spoiled brat.

You heard it here first: I'm saying she'll be busting out naked Miley-like leaks in the next 3 years.
