"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 realizing 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..." 
The video was shot by production company LUT! MED!A and director RAGE in Central London near Tower Bridge. A few seconds of the video was shown on the album advert and images from the video and behind the scenes are featured on the album booklet. The video premiered on Clubland TV on 19 November 2009. All Around the World uploaded the video on their YouTube channel the next day. The video starts with skyscrapers and a transparent "N-Dubz" logo, it then reads "Playing with Fire" with the word "Fire" in a large font on fire. We then see each member of N-Dubz with their names on the screen, we then see Mr Hudson with "featuring Mr Hudson" on the screen, it uses Mr Hudson's official logo. The video cuts to N-Dubz and Mr Hudson performing in front of Tower Bridge throughout the video. Mr Hudson sings his verses in front of a set of telephone boxes. Dappy is then seen in an apartment cheating on his girlfriend and getting caught, his girlfriend walks out the room and is then seen crying. Tulisa is in a hotel room watching her boyfriend sleep, she then takes his phone and starts reading his texts, she looks disgusted then wakes her boyfriend up, they begin to fight and Tulisa storms out of the room and gets into a limo and begins to cry. Fazer is seen driving a car with a girl in the passenger seat, they begin to fight and Fazer rings up his mates G-RYD to help solve his issues. The video ends with the N-Dubz logo. The video received over 10 million views on YouTube before the single was released. It now has over seventeen million views.
