Before this lil girlie sippin' on her baby bottle turned into an on-stage performer who tops the music charts, she was just tossin' back the milk, and growing up in Wisconsin and Virginia ... before movin' to sunny Los Angeles at 14 years old.

Upon her SoCal arrival, she adopted her stage name which is not to be disclosed at this time 😜, however when you listen to her music you better turn up the volume to the MAX!

"Oh, she's sweet but a psycho, a little bit psycho!" ... Her words, not ours 😉!

Can you guess who she is?
