Agree with @SinglePringle - Madonna has earned the right to do what she wants. Leave her alone FGS. If she didn't do anything, (to herself) she would be accused of letting herself go, and looking old and wrinkly.
She is not the best singer, and has never claimed to be. She is an artist, a songwriter, and a dancer, and a singer. She said once that she knows her voice isn't great, but she has always had something to say, (and that's why she writes lyrics,) and she loves to dance and entertain.
Yeah it's a bit awkward seeing her interviewed sometimes, because she can be a bit touchy and maybe takes offence easily, or thinks people are having a go when they're just having a laff, but on the whole, the interview wasn't THAT bad.
I don't think she is unpleasant at all, she is just a bit aloof in interviews, (sometimes,) and doesn't suffer fools gladly.
She's just Madonna, she isn't a great singer, she may have had a bit much botox, and she is a bit cool sometimes.... But she is MADONNA, she is a great performer, her lives shows are ace, (seen her 3 times,) her songs are very good, she has had an illustrious non-stop career for almost 40 years (so far,) she has had 13 number 1 UK hits, 63 top 10 hits, she has spent 15 years out of her career in the top 75 singles, she has sold over 330 MILLION albums, and she is still going strong, entertaining people, and enjoying her life.
I'd like to know what her haters and beraters have done with THEIR lives? Fuck-all I expect! 
No I am not her OR her PR manager. I am just a fan of hers for 36 years!
Sorry, but you don't maintain the level of success and fame MADONNA has, (for almost 40 years,) if you are shit!
