"Little Bad Girl" is a single by French DJ David Guetta, featuring vocals from English recording artist Taio Cruz and American rapper Ludacris. It was released for digital download from 27 June 2011 by Virgin Records, serving as the second single from Guetta's latest studio album Nothing but the Beat. This song later appeared on Cruz's third album TY.O.

All three artists co-wrote the song with Frédéric Riesterer and Giorgio Tuinfort, both of whom co-produced the song with Guetta as well as Black Raw.

This is the first of two collaborations between Cruz and Guetta, as Cruz would later co-write Guetta's single "Without You" featuring Usher. This is also the first of two collaborations between Ludacris and Guetta, as the two would later collaborate on the 2012 song "Rest of My Life" also featuring Usher. This is also the second collaboration between Ludacris and Cruz, after Ludacris appeared on the US version of Cruz's single "Break Your Heart".

The music video was released on YouTube on 11 July 2011. It features Guetta hosting a beach-side disco party called "Endless Night" (which he wants to literally never end) with Cruz and Ludacris in attendance. When Guetta sees the sun start to rise, he and many other guests run down to the beach and they all skid to a halt in front of the sea, causing the Earth to rotate backwards. The sun goes back down and this makes it dark again in other parts of the world when it had just been light. Ludacris can also be seen with a megaphone when rapping his verse. Towards the end of the video, the sun again starts to rise and Guetta runs off to repeat what he did before.
