"Troublemaker" is a song by English recording artist Olly Murs, released as the lead single from his third studio album, Right Place Right Time (2012).

"Troublemaker" was written by Olly Murs along with Claude Kelly and Steve Robson, with whom he also wrote his previous hits "Please Don't Let Me Go" and "Dance with Me Tonight".

Described as an "airy pop anthem" the songs' instrumentation consists of "lightly funky, guitar-led backdrop", which some critics have compared the guitar riffs to Maroon 5's "This Love" and "Misery".

[9] Robert Copsey of Digital Spy gave the song a four out of five star rating, praising its composition, but he criticised Flo Rida's appearance, describing it "confusing, [...] but if it makes Olly a hit across the pond, we suppose we can let it slide.

"[10] Idolator's Robbie Daw echoed Copsey's comments describing the song " a total disco-pop winner, and would stand on its own without [Flo Rida].

An American casting agency site revealed in their advert that the story of the video revolves around Murs and a female lead who is "so ditzy she keeps getting fired from her jobs, and by coincidence, keeps crossing paths with Olly.

"[23] Another casting agency released a montage of pictures from the set of filming of the video on their Facebook page on 26 September, including a shot of Murs being arrested by a police officer which did not make the final version.

[26] The video starts with Murs entering a cafe, where he sees a young woman (played by actress Danielle Beckwith) working as a waitress there.

The video ends with Murs seeing the woman again, this time in a nightclub with friends where she accidentally knocks over a man carrying a tray of drinks, setting off a further chain of arguments.

Murs comes to her rescue and the two begin to leave but are stopped by one of the club's bouncers and the screen cuts to black with the word "Troublemaker".

[27] The live performance showcased his vocals in a laid-back alternate take on the song which was backed with a string section and further male vocalists.

[27][28] Trent Maynard of 4Music described the performance as "stunning" and praised Murs for "nailing flawless vocals" and his "star power" without the presence of Flo Rida.

[29] "Troublemaker" was performed for the first time on 12 October 2012 at "Love Music Live" gig organised by Heart Radio in London.

[32] In April 2013, he made a guest appearance on the fifth season of the American drama series, 90210 as himself and performed "Troublemaker" and "Right Place Right Time".
