Thank  you so much!!! and the singer is Lee Youngji, not to be confused with another Youngji that was in a Kpop girl band.  

No, the rapper is Lee Yong Ji.  She's only 20 or 21 and has already won awards.  She's been rapping professionally since she was in high school.  I like her.   Although her image is changing, she'd never be confused as an idol for a girl group.
