The N-Dubz star's account on the microblogging site began hosting pictures of explicit text conversations supposedly with his love interest Amina Snooks on Tuesday, and also displayed her phone number.
Most of the tweets have since been deleted.
Snooks subsequently took to Twitter to reveal that Dappy's phone had been stolen and assure her followers the posts were not from him.
Hours later, on Wednesday, Dappy tweeted that his account had been hacked and police are investigating the incident.
