They aren't stans, they just like some of these artists: both of them like Madonna, Mariah Carey, also my dad likes Beyonce and my mum Britney and Katy Perry.
My dad really does not care for stanning hahah but my mom is really into Katy Perry, Rihanna & Lady GaGa while listening to the radio in the car....also she stans a lot for Kelly Clarkson, thanks to me though hahaha
