But during her spell as guest judge, Victoria Beckham got to see a lot more than that from one contestant who ended up performing a mini-striptease in his audition.
After her recent debut on the reality show, Posh was back on US TV screens this week, joining Simon Cowell, Randy Jackson and Kara DioGuardi on the judging panel in Denver.
One member of the public she met was 27-year-old Texan Casey James, who, like all the hopefuls, was keen to get through to the next round.
After failing to impress Simon when he sang for the quartet – the music mogul told Casey his performance had "no charisma, no effort" – the female judges were keen to defend the musician.
Fashion designer Victoria certainly saw potential, saying she thought he had a "great look" after asking him to take his hair down, and agreeing with Kara that the Fort Worth singer looked "like a model".
It didn't end there.
Singer-songwriter Kara then encouraged Casey to show a little more flesh by "unbuttoning your shirt a little bit", before Randy joked: "Or why not just take it off?" – which is exactly what he did.
It might have been an incredibly awkward moment for the topless wannabe, and indeed the panellists, but it did the trick, and Casey received enough votes to go through the next stage.
Victoria's profile in the US has been greatly increased by her Idol appearances, and American viewers have the chance to see her in action again later this month as a guest presenter on popular chat show, The View.
