Baby Stase (born Stason Betha) is an Harlem rapper best known for being the twin sister of Ma$e. She is a member of Harlem World, the group Ma$e formed and signed to his All Out Entertainment label—they released their gold-selling debut album The Movement in 1999 on So So Def and Sony Music. Stase rapped on the group’s lead single “I Really Like It.”
In 1999, Stase told MTV:
With [Mase] being my sibling, sometimes it can be a little difficult. But it’s fun overall because I know he’s on my back and he’s being hard on me because he wants to see me prosper. With us all, he wants to see us do just as well as he did when he first entered the music business
