Cassie fires up the screen in the sultry teaser for “King of Hearts,” the first offering from her upcoming sophomore album, due in 2012 on Bad Boy/Interscope.

“I don’t want to call it dance ’cause it’s not dance, but it has a dance vibe if you want to say that,” said the Bad Girl of the electro-dance production. “If we were in this room playing it right now, everybody would just be hanging from the lights.”
