Lil Scrappy is messing with SUPERHEAD?!

Rapper Lil Scrappy and Superhead are KICKIN IT. The two sent each other flirtatious twitter messages, and Karrine asked him to DM her personally, which he did.

Karring called him an "old friend." Given the fact that Karrine uses HER JAWS on every man she knows . . . that means they had RELATIONS.

We've been told that Scrappy has been LET GO from Love And Hip Hop Atlanta . . . and that Karrine ain't got a job neither. So it could just be a PLOY . .. to get the two of them to join NEXT SEASON'S CAST.

What do y'all think? Would you watch Love and Hip Hop with SUPERHEAD . . . or is she too washed up.
