The 27-year-old told Brisbane hit105's Stav, Abby & Matt with Osher on Thursday: 'No, I don't have bum implants!'
Iggy's shapely derriere has undergone a formidable rise since her days as a aspiring pop singer.
Appearing on Brisbane breakfast radio, the hosts complimented the rapper on her shapely figure but questioned whether her 'unreal' shape was down to butt implants.
'No I don't have bum implants!' Iggy said. 'They aren't my real boobs, but it is my real bum.'

'I do have a small waist, I have to work on it - I am never allowed to eat what I want,' Iggy complained.'Four months ago, I got bigger boobs! I'd thought about it my entire life,' she told Vogue in 2015, adding she initially didn't want to tell anyone but decided 'I wasn't into secret keeping'.
Later that year she admitted to having her nose altered, telling Seventeen magazine: 'Denying it is lame!'
Iggy did say she did not plan to completely change herself, adding: 'It's important to remember you can't change everything. You can never be perfect.' Dailymail
