Presumably Fat Cat is using "bad boy" in more or less the way Larry Williams used it (not to mention G-Dragon, who says in "Tonight" that he's a bad boy but he's nice).

Do you know anything about Fat Cat and "My Love Bad Boy": whom she records for and is signed with, who wrote and produced the song, etc.? I haven't searched strenuously, but as of a couple of weeks ago the only background I came up with was the claim at allkpop.com that the choreographer was the person who'd choreographed Lee Hyori's "U-Go-Girl."

Seems strange that a new act would be launched without an MV.
