Professor Green strikes again, this time calling Kristen Stewart a 'cheating slutbag'. Someone needs to keep him away from Twitter for a while. Unless this has earned him back the followers he lost due to over shooting his mouth the day before yesterday.

Just this week Green was already in deep sh*t for making light of the very serious eating disorder, bulimia. You can read all about why he thinks it's the "most intelligent" of all the eating disorders here. Today however he turns his sharp tongue towards the one person we cannot stop talking about, Kristen Stewart.

As per Digital Spy the rapper has branded Stewart a 'sl*tbag' at the same time as declaring that she has committed "career suicide" by "incurring the wrath of Robert Pattinson fans through her 'fling' with Rupert Sanders."

For those of you who can't get enough the Professor's latest musings, his exact tweet said: "Being a cheating sl*tbag aside i actually feel sorry for Kristen Stewart... She may as well have cheated on justin bieber. #careersuicide."
