British rap sensation Professor Green has given his opinion on the tweets sent out by Rob Kardashian earlier today about Rita Ora and slammed girls for jumping on the 'hate' bandwagon.

Kardashian took to his Twitter page this morning (December 3) and slammed former lover Ora for supposedly cheating on him with 20 men, and Green has since told users of the social networking site that girls are the worst for hating on others.

"Girls need to drop the Rita hate. One tweet from an ex she left and you're gassing? Begging for an excuse if you ask me. Lame."

"That's something I never expected... Rob K. 'fans' tweeting me. Alright then... Back to my evening."

Green also joked that he's been brushing his teeth with bottled water: "Brushing my teeth with evian. no, i haven't changed - a pipe has burst and i have no water. #sh*tsunday"
