Professor Green, Wiley in Twitter spat

Professor Green and Wiley have clashed over Twitter, as Wiley attacked the rapper's music and career.

Earlier today, the grime MC claimed that white rappers would not be around in mainstream music if it weren't for Eminem's success.

Referring to Green, Wiley said that while he respects his talents as a battle rapper, he does not rate his music.

In response, Green tweeted: "I will always be a fan, but that's not to say I won't s**t all over you. It's not a problem for me."

Wiley and Green continued to trade insults, while Green's fans also got involved.

As Green attempted to diffuse the situation, Wiley continued to tweet about the disagreement, and denied starting the argument.

However, he seemed unfazed by the extra attention, later saying: "im going now and remember these 2 words 'viral marketing' (sic)."
