I think it is not just because Madonna is old at this moment. It is just because she tried to make something special out of her pop star life, trying to change the world in a big manner through her music and dance and she failed in the eyes of many. She still tries that and that's why people make fun of her age. She didn't succeed when she was younger. But as you see, Gaga is making history through every aspect of her life, creating amazing music, receiving countless awards for this and for peace, fashion, charitable acts and more. This is just my opinion, you can disagree, but we both know how Gaga's ascending compared to all other stars.
Its sad to see shitty post like this on the hot's because sometimes people make amazing art and get 2 likes and this offensive post is getting more than 300. Stop!! gaga will be old one day too, Madonna was born a lot before than gaga
