Madonna has revealed that her children are often some of her harshest critics.

The Queen of Pop told The Sun that her kids have "no tact whatsoever" when it comes to telling her what they do and do not like from Madonna's catalogue.

However she is happy that they are being honest about their mother's work. She said:

"My kids are brutally honest when it comes to what they don't like. They have no tact whatsoever. They'll just say, 'Mum, get that song off' even when mine. It's hurtful but at least they're honest."

Madonna meanwhile added that her upcoming world tour in support of new album 'MDNA' will be a feast for the "eyes and ears". She said:

"There's been lots of cardio and I'm doing a combination of pilates and dance cardio. And there's been plenty of skipping rope work. The envelope I'm pushing for is as spectacular a show as I can. It should be a feast for the eyes and ears."
