The N-Dubz star released his latest freestyle 'I'm Coming (Tarzan Part 2)' yesterday (July 3).
In the track, he mocks the likes of Simon Cowell, Joe McElderry and Alexandra Burke. Cousin Tulisa Contostavlos criticised the song, claiming that her former bandmate has "lost his mind".
Allen tweeted: "Dappy's new tune is jokes, in a good way. Thoroughly entertaining and insightful which is more than I can say for most things on the radio.
"And also, since when is pop music meant to be politically correct? Why people are so shocked by it is beyond me."
Allen recently confirmed that she is back in the studio, working on new material with Greg Kurstin.
Dappy's debut solo album Bad Intentions will be released on October 1.
