Update: 13th July It seems MTV jumped the gun a little with the Season 2 Renewal announcement. MTV have since removed that tweet and said it has not officially renewed the show yet.
Exec producer @JaimePaglia just made an announcement at our #SDCC panel...THERE WILL BE A SEASON 2 OF #MTVSCREAM. HELL YES.
