I'll be intrigued to see how Madonna and Kylie will fare with their new albums
There's a whole world, (and an age difference) between the two. Why even compare? It's irrelevant. I'd hate to be compared to people 10 years older than me. Let each artist go about their own way. I'm sure at 56 Kylie will be doing her own thing.
I can't even imagine Kylie wanting to strut her stuff at the grand old age of 56. Kudos to Madonna though. She has a fab body.
