Cheryl's popularity grew significantly during her stint on "The X Factor" in its heyday, and the British press called her a "nation's sweetheart". As a judge, she was noted for her style, "disarming compassion and sensitivity". "The Telegraph"s Bryony Gordon dubbed her a "Princess Diana for the "X Factor" generation." Cheryl also received criticism. In 2010, "The Guardian"s Simon Hattenstone wrote about the public perception of her: "One day she might be the stoic saint coping with marital adversity or the Mother Teresa of "The X Factor", smiling beatifically as her kids perform for her; the next she might be the hard-nosed bitch who lip-syncs her way through a "live" TV performance while her "X Factor" wannabes have to do it for real, and who is happy to advertise L'Oréal shampoo while wearing hair extensions." Alice Vincent of "The Telegraph" remarked that "Cheryl's career has been pockmarked by tales of demanding behaviour and superciliary attitude". Gordon, however, described her as being "self-critical" and "very polite about everything".
