Costadinos Contostavlos[1] (Greek: Κωνσταντίνος Κοντόσταυλος; born 11 June 1987), better known by his stage name Dappy, is an English rapper, singer, songwriter and actor.

His first taste of solo stardom came as a guest artist on label-mate Tinchy Stryder's single "Spaceship", which was released in June 2011.

While deciding upon his debut solo single, Dappy was contacted by Def Jam, asking him what he would like done with the demos of a track N-Dubz had recorded whilst under the label, which remained unreleased.

Featuring a cameo appearance from band-mate Fazer, "No Regrets" took the charts by storm, peaking at #1 in the UK and Scotland, and at #8 in Ireland.

Following the success of "No Regrets", Dappy claimed during an interview that: "With my solo stuff, I really want to earn the respect of an older audience.

However, it didn't do as well with the media and was heavily criticised for a scene in which Dappy is standing outside a block of expensive luxury flats with a "rich kid" who is trying to look like a gangster.

The Independent wrote, "His lyrics combine jealousy with anger: 'You got too much to lose / You're in a great position... You wouldn't last a minute where I'm from / You'd go missing / So appreciate what you got / 'cos I'm still wishing.'

The silent boy falls instantly to the pavement ... Do scenes like these suggest that music videos are encouraging their viewers to indulge in criminality?".

The show received a text message from a woman in Boston, Lincolnshire, complaining that Dappy was "vile" and "a little boy with a silly hat" and that N-Dubz were "losers".

Dappy secretly copied her phone number from the studio console and, the following day, tried calling her and sent threatening messages including: "Your [sic] gonna die.

In December 2008, Dappy pleaded guilty to two accounts of assault at Chelmsford Magistrates Court, Essex after reportedly spitting in a woman's face while drunk on a night out.

Dappy pleaded guilty to the offences and for each count received four weeks' imprisonment, suspended for 12 months, to run concurrently and 100 hours community service.

[22] In January 2013, he was found guilty by a jury at Guildford Crown Court of assault and affray and given a suspended sentence of six months imprisonment.

[24] In 2017, Dappy was convicted of possession of a bladed article in a public place following an altercation with his partner and given a suspended prison sentence.
