What happened to Kid Sister?

I remember Kid Sister was being set up to take over the female rap game and then all of a sudden...nothing happened. She had a dope track with Kanye West and had the support of producer/DJ A-Trak. Everything was beginning to look good for Kid Sister. She was going to hit fame but her vigorous energy has died down. She is still making music but I was expecting her to be the next big thing. Can she still or has her time passed? Here is a fun video feat Kanye West.
