Dappy was told off twice by a judge in court yesterday.
The 24-year-old rapper - whose real name is Costadinos Contostavlos - is charged with affray along with three fellow defendants, and the quartet were told to be quiet as they tutted and talked during evidence at Guildford Magistrates Court, Surrey, according to The Sun newspaper.
Dappy has been hit with the charge along with the trio - Kieran Patrick Vassell (aged 24), Kalonji David Stewart (aged 31), and Alfred James Miller (aged 27) - after the group allegedly got involved in a brawl at a Shell petrol station in Guildford last month, leaving three men with "serious facial injuries".
The 'No Regrets' hitmaker and a friend are said to have pulled up at the garage and approached a group of girls and three men, and they asked the women to join them in their car.
But when Dappy and his friend's advances were refused, one of them is said to have spat at the women before a group of six men arrived in two cars and a fight broke out.
The N-Dubz star's lawyer Adel Buckingham, said: "He totally denies the allegations against him and he is indeed keen to clear his name."
Dappy dressed smartly in a dark suit and white shirt for his court appearance and he stopped to hug fans after he left the building.
All four deny affray and claim Dappy was attacked. The quartet have been given unconditional bail and are due to return to court on July 19 when the case is expected to be committed to crown court.
