"Untouchable" is a song performed by British all-female pop group Girls Aloud, taken from their fifth studio album Out of Control (2008).

The "emotional twangy guitar noise" heard in the song was the result of Xenomania musician Jason Resch responding to Higgins' request for something "special".

[3] In interview with The Daily Star, band member Sarah Harding commented on the track: "When we first heard [it] we thought it was so Nineties, a proper pop dance song.

"[5] "Untouchable" was selected as the third single from Out of Control after it fared best in a fan poll on Girls Aloud's official forum.

"[9] The 7" vinyl picture disc format includes the Thriller Jill Mix of "Love Is the Key", as heard on The Girls Aloud Party opening credits and commercials.

[11] In a blog for BBC, Fraser McAlpine agreed that "it's epic and dreamy and a bit of a diversion from the usual GA pattern while still being recognisably very Girls Aloud.

[14] Talia Kraines of BBC Music felt "the Balearic bliss of epic seven minute marathon Untouchable [...] prove[s] that you don't have to be brassy to be brilliant.

"[15] Michael Cragg from The Guardian called it a proper "statement song", as well as "the band's most effortless-sounding single" without ever feeling overly long.

[16] Nick Levine of Digital Spy said the song "serves as the centrepiece" on the album and that even the radio edit "remains surprising, thrilling and strangely moving - in short, classic Girls Aloud.

[22] After the single failed to achieve top ten success when it was released late April 2009, a fan-created Facebook campaign was started nearly a year later (January 2010).

The group hoped to push the single into the top ten, reviving and continuing Girls Aloud's streak.

[4] After the second verse, the words "Alert: Condition Red" appear on the screen and the girls have trouble in their bubble-like force fields.

The video ends with televisions showing the breaking news as they hit the ground, with a reporter describing it as a "meteor shower" before turning to static.

Girls Aloud entered on wires suspended from the ceiling and performed the song whilst ice dancers Torvill and Dean skated around them.

The song is "performed over the crowd on a flying platform,"[32] which Girls Aloud used to travel to a smaller stage in the middle of the arena.
