The 25-year-old star has been found guilty of affray and one count of assault.

NDubz star Dappy is facing up to three years in prison after being found guilty of assault and affray for his part in a petrol station brawl.

The 25-year-old N-Dubz singer was convicted by a jury at Guildford Crown Court in Surrey in connection with a fight at a Shell station in Guildford in February 2012. He appeared in court along with two other men.

During the trial, the court heard that Dappy, charged under his real name of Costadinos Contostavlos, instigated a "mob-handed attack" during which he beat up and spat at David Jenkins.

Jenkins suffered several broken teeth in the fight while another man, Oliver Billson, suffered a swollen eye and Christopher Gibson suffered a broken nose.

According to prosecutors, Dappy turned on Jenkins after he stepped in to protect Grace Cochran and Serena Burton, with whom the London-born star had started an argument.

The court heard that Dappy became angry after the teenagers "dissed him" and rejected his advances.

The father-of-two was found not guilty of two common assault offences, which included spitting at Cochran and Burton, both 19.

Co-defendant Kieran Vassell, 25, of Hammersmith, west London, was found guilty of affray, while Kalonji Stewart, 32, of Harborne, Birmingham, was found not guilty of the same offence.

Following the guilty verdict, Dappy, whose cousin and former bandmate is X Factor judge Tulisa Contostavlos, headed online to vent his anger in string of tweets.

He told his 504,000 twitter followers: "Not guilty For spitting at the Females but Guilty for defending my self from the 3 Males!!!! #ThisAintRight."

"'U see... I told u I never Spat at No Girl!!!!! #ThisAintRight."

Presiding judge Neil Stewart adjourned proceedings for pre-sentence reports to be prepared on Dappy and Vassell.

The cases have been adjourned for 15 February and the pair have been released on unconditional bail until then.
