no. the cw has oth for a 7th season. as far as i know, most of the charcters/actors will be back পরবর্তি season. chad is negotiationg right now, because apparently he wants to be in s7. and so i think if he signs on hil might too, because then their storyline for her may change into something she likes. :)
They have renewed the প্রদর্শনী for season 7, but it is unclear if chad অথবা hilary are coming back. I also read on wikipedia that the cw has renewed it up to season 10
