It is the final single to feature the group's third line-up, prior to founding member Keisha Buchanan's departure in September 2009.

The song's accompanying music video was directed by Emil Nava and features the group's members in a house of mirrors, a bird cage and a room covered in graffiti.

[1] They signed a contract with Jay Z's record label, Roc Nation, resulting in working with high-profile producers .

[6] In an interview for Digital Spy, Keisha Buchanan said that the response to the song was great, saying: "From the beginning there's been a real buzz about the track.

She did say that she enjoyed working with Mars and would like to collaborate on a new song with him and founding Sugababes members Mutya Buena and Siobhán Donaghy.

As a result, "Get Sexy" was re-recorded along with a number of other tracks to feature the vocals of new member Jade Ewen in place of Buchanan for the release of Sweet 7 in 2010.

[13] According to Digital Spy, in an interview with Teletext, Buchanan revealed that inspiration for the song came "by accident", saying: "The producers were messing around going, 'I'm too sexy for the studio'.

[15] David Balls of Digital Spy gave the song a four out of five star rating, saying: "'Get Sexy' is a dancefloor stomper that nestles somewhere between 'Boom Boom Pow' and 'Bonkers' in its blend of electropop, techno and R&B sounds.

It may not be massively original, nor an instant classic to rival 'About You Now' or 'Push the Button', but with a Right Said Fred-sampling hook, a thundering chorus and plenty of attitude – most noticeably from Amelle – it returns Sugababes right to the forefront of the pop landscape.

[17] Fraser McAlpine of BBC gave the single a mainly negative review, calling it a "mess" which has "not bothered to make it rhyme" in the way the original, 'I'm Too Sexy' did.

[18] During the first week of its release, "Get Sexy" was ahead of its nearest competitor, "Run This Town", by Jay-Z featuring Rihanna and Kanye West, at number one.

[35] The video features Berrabah in a bird cage, Buchanan posing on a couch and Heidi Range in a house of mirrors shot at by intense light beams.

[36] Popjustice praised the video, saying that it "seems to feature Sugababes 3.0 as 'the full package', and makes sense of this lineup, for the first time.
