Dappy is currently working in Oxfam
Dappy is spending his community service hours working in charity shop Oxfam.
The N-Dubz star has 150 hours of commuminty service to complete after being found guilty of affray and assault.
The 26-year-old rapper - real name Costadinos Contostavlos - took locals by surprise when he was seen completing community service at a branch of the Oxfam chain in Hertfordshire.
A source told The Sun newspaper: "A few people have been shocked to see Dappy in the shop.
"He's been getting on with it though, and helping Oxfam out as he serves his time."
While he was found guilty of affray and assault in January of this year, the 'No Regrets' star escaped jail and was instead given a six-month suspended sentence, over £6,000 in fines and community service.
Dappy's conviction stems from an incident on February 28, 2012 at a petrol station in Guildford.
The star allegedly spat at and verbally abused Grace Cochran and Serena Burton, both then 18.
Dappy is then said to have got into a brawl with a concerned onlooker, David Jenkins, who intervened on the girls' behalf. He allegedly spat at the man, put him in a headlock and punched him.
