You can talk to her, but she has no dialogue options. That or only Rumors. And there is a quest where you have to kill her, the Daedric Quest for Clavicus Vile. Be careful, though, that quest is prone to crashing the game. Save before starting it and read this site's page for ways around the bug. Also, be careful during Molag Bal's Daedric Quest, that one has a bug where you lose all your racial and attribute bonuses. Permanently and irreversibly.
