Nikki Osborne Instagram – Well the mullet dress was a hit! Performing at the Sydney Opera House last night felt like a dream. The line up was amazing and everyone crushed it. A special thanks to @sooshimango for inviting me to perform alongside them. @joewhite_official @troykinne @ibby_a @mycousinvlad @effiegoodthanks @mewmewsofficial @justforlaughs_syd @moretalentau
