Former N-Dubz star Dappy has been charged with affray following an alleged petrol station punch-up near the rapper's studio.
The 24-year-old, whose real name is Costadinos Contostavlos, was arrested along with three other men at a Shell garage in Guildford in the early hours of 28 February.
Surrey Police alleged that Dappy, whose cousin is X Factor judge Tulisa Contostavlos, and another man approached two girls and three men at 3.30am and asked the girls to go with them.
An altercation broke out between the two groups and another group of up to six men who arrived in two vehicles.
A police spokesman said: "The trio of men were assaulted and received serious facial injuries in the attack."
The men charged with Dappy are Kalonji Stewart, 31, Kieran Vassell, 24 and Alfred Miller, 27.
All have been bailed to appear before Guildford magistrates court on 24 May.
Dappy has enjoyed success since he went solo in 2011 after his spilt from N-Dubz. His debut single, No Regrets, scored him his first No 1 as a solo artist. He has also recorded his hit Rockstar with Queen legend Brian May.
