Madonna says she looks to her children's music tastes for guidance.

The singer looks after four kids - daughters Lourdes, 18, Mercy, nine, and sons Rocco, 14, and David, nine.

Speaking to Italy's Che Tempo Che Fa, the Queen of Pop suggested that she uses her children to gauge the quality of new songs.

Madonna said: "I have asked their opinion. I always do it. They were with me a lot in the studio. I rely on their taste. I follow their opinion.

"They have good taste! But it doesn't mean they like every song. They have strong opinions."

The singer released her new album 'Rebel Heart' in the UK on Monday (March 9).
