"Playing with Fire" is a song by English hip-hop trio, N-Dubz featuring Mr Hudson. The song is the second single taken from N-Dubz' second album, Against All Odds. The meaning of the song is a girl realising that her boyfriend is cheating on her and trying to get him to confess. It shows both the man and the woman's point of view. It shows their communications with each other when the woman confronts the man.

Mr Hudson announced via his Facebook site that N-Dubz and he had recorded the song and shot the video. The single was to be released on 11 January but was pushed to 25 January because the previous date was the same as the single release of Mr Hudson's other collaboration with Jay-Z, "Young Forever". It was then pushed forward to 18 January.

Nick Levine of Digital Spy gave the song a positive review. "Their Tinchy duet's been longlisted for Best British Single, but would it have killed the Brits panel to give N-Dubz a proper nod? After all, the Camden crew are now a sufficiently mainstream concern to count Gary Barlow as a songwriting partner, spearhead a charity single, and... erm... get themselves a ticking off from the School's Secretary. Anyway, a single like 'Playing with Fire' shows why they've risen from the pirates to the Radio1 A-list. With its catchy call-and-response chorus and easily relatable lyrics - Dappy plays the no-good-cheating-sod, Tulisa the smart cookie who calls him out - it's another contemporary pop cracker from the trio. Mr Hudson even turns up for a savvy bit of fanbase-mashing. Just one thing - in the light of recent events, it's hard not to fear for Tulisa's blood pressure when she starts singing about checking Dappy's texts. Let's be honest, That Other Woman could be the least of her worries..."
