Dappy has been found guilty of affray and one count of assault by beating after an altercation at a Surrey petrol station on February 28 last year.
The musician was cleared of two other counts of common assault when the verdict was read out at Guildford Crown Court today (January 17).
The 25-year-old - real name Costadinos Contostavlos - had been accused of spitting in the direction of 19-year-olds Grace Cochran and Serena Burton on the Shell forecourt on Woodbridge Road, Guilford before an altercation with bystander David Jenkins, who had intervened.
The rapper was charged with two counts of common assault on Cochran and Burton, one count of assaulting Jenkins by beating - which involved him spitting at him - and one charge of affray.
The N-Dubz star was cleared of the charges of assault against the two women, but guilty of the latter two offences.
The case was adjourned by Neil Stewart for the preparation of pre-sentence reports.
Dappy and Kieran Vassell, 25, of Hammersmith, West London - who was also found guilty of affray as a result of the incident - will be sentenced on February 15.
Both have been released on unconditional bail until this date.
The court was told that Dappy had attempted to persuade Cochran and Burton to come into his car, but they instead ridiculed him.
Dappy denied attempting to chat up the girls, instead claiming that he spoke to them only to promote his new single.
He then alleged to have spat at, but missed, the two girls - but he was found not guilty of these common assault charges.
After Jenkins intervened, Dappy spat at Jenkins, and the court heard that saliva with a DNA link to the musician was found on his T-shirt.
Jenkins then put Dappy in a headlock, prompting Dappy's companions to join the altercation.
The court heard that several of Jenkins's teeth were broken in the fight, while two other men also suffered facial injuries.
Dappy had been tried with Vassell, and Kalonji Stewart, 32, of Harborne, Birmingham, who were both charged with affray.
Vassell was found guilty, but Stewart was found not guilty.
28-year-old Alfred Miller of Brentford, West London, had already pleaded guilty to the charge of affray, but his case was adjourned for sentencing until the end of this trial.
