It is bad enough making a bit of a mistake in your workplace. When your workplace happens to be the US Dancing with the Stars finale, in front of a live televised audience of more than 11 million viewers, you're in nightmare territory.
Such was the case for the Australian singer, MC and model Iggy Azalea on Tuesday night, when her in-ear monitors malfunctioned, throwing her off her vocal as she performed her current hit Fancy.
Iggy Azalea's awkward earphone malfunction
Australian rapper Iggy Azalea recovered remarkably during a performance at the US final of Dancing with the Stars after her in-ear monitors malfunctioned, throwing her vocals out of sync.
"I'm so sorry but there's something wrong with my ear," Azalea was forced to say a couple of lines into the song - lines which had awkwardly overlapped out of sync with additional vocals from a backing track.
Yet after silently continuing with the performance's choreography, which had her walking down a staircase as the queen of the prom with her "king" (a dancer), Azalea pulled her monitors out of her ears, apparently listened to what everyone else in the audience was hearing and staged a remarkable recovery.
By the time Brit singer Charli XCX chimed in with her guest spot on the song, you wouldn't have known there had been any problems. The rest was virtually flawless.
Nonetheless Azalea apologised to her fans on Twitter, acknowledging "the dramas of live TV".
"S--- happens," she continued. "Still really enjoyed it."
Fancy is the fourth single from the 23-year-old's debut album The New Classic (also the words on her "prom" sash) and her biggest international hit to date. It is currently No.3 on the Billboard Hot 100 singles chart, having this week swapped places with the No.4 song, Ariana Grande's Problem ... which itself features a guest spot from Azalea.
The New Classic initially peaked on the Billboard album chart at No.3 but looks set to head back up following the success of Fancy. The longplayer has already created history as the first by a non-American female MC to top Billboard's rap albums chart.
