Unfortunately, there hasn't been any official word on a seventh season yet. Last year we learned while season 4 was still airing that season six was "green lighted", so hopefully we'll hear the same of said season 7 before long. I can certainly picture it being green lit again, still being popular and all. But the folks at CN might not think it's worth it another year, with the end of BFAHP and all. It's still a high probability, though, of it coming back for a lucky #7. I'm sending telepathic messages to CN saying "Don't you dare! Don't you dare!! DON'T! YOU! DAAARRRE!!!"
