My mom constantly 'confuses' Christina Aguilera for Lady Gaga and TBH I think she does it on purpose to annoy me. The only thing my dad has ever said about her was that he liked her song 'Impossible' when it came up on itunes and even added it to his playlist. So that's enough for me.
My mom and grandma love Gaga and my mom HATES Katy
My dad ain't into any of that, all I've heard him say about Gaga is "she's just like another Madonna but she's not even pretty" and "at least she can sing"
