Mauboy's weight has been the subject of media interest, ever since her rise to fame on "Australian Idol" when judge Kyle Sandilands publicly told her to "lose the jelly belly". Mauboy told "Women's Health" magazine that she was proud of her curvy figure, saying "having curves is one of my favourite things". In 2014, she received media attention for her weight loss transformation from a size 12 to 8. Mauboy has an alter ego named J Malley, who she described as her "fearless side" and "sort of like Beyoncé's Sasha Fierce". Mauboy is often referred to as Australia's answer to Beyoncé. However, she does not agree with the comparisons, saying "I totally disagree with that one. I've...watched her documentary ["Life Is But a Dream"] and was just blown away by how magnificent she really is and it's so inspiring for me. I just think she's fantastic and I'm completely nowhere near where she is, but I aspire to that."
