Singer Iggy Azalea wants to "crawl into a cave" sometimes and says she doesn't think it is possible to be "confident 100 percent of the time".
The "Fancy" hitmaker, who recently sparked speculation she has had a chin implant, admits she still struggles with poor self-esteem, reports femalefirst.co.uk.
The 25-year-old singer said on the "Today" show: "Some days I want to crawl into a cave because I don't feel confident at all, and then other days I feel great."
"I think it's like that for all human beings, not just young women. I think being confident 100 percent every day is something to aspire to, but I don't think it's humanly possibly for anybody."
Azalea is engaged to her long-time boyfriend Nick Young, and she plans to wed in the US in 2016 because his family is too large to fly to Australia.
