Most of the time, it's Cláudia who is compared to Ivete, as Ivete came first. However, at one point during the first Kids season, contestant Larissa Carvalho mistakenly referred to Ivete as "Claudinha" (a pet name for Cláudia), resulting in a flabbergasted reaction from Ivete that achieved Memetic Mutation status on social media. The whole moment can be seen here, starting at the 0:11 mark.
