Pop diva Madonna has been accused of using the Charlie Hebdo massacre to promote her upcoming album 'Rebel Heart'.

Two gunmen killed down 12 people, including journalists and two policemen on Wednesday at an attack on satirical magazine Charlie Hebdo, reported New York Post.

The 56-year-old star Instagrammed a 'Je Suis Charlie' image on Wednesday, sharing words of peace while also hashtagging her own album title, 'Rebel Heart'.

"These are very scary times we are living in. Ignorance breeds Intolerance and fear. We can only fight darkness with light! We are all Charlie! revolutionoflove #rebelhearts," Madonna wrote.

She posted a picture of Parisian protesters, saying, "We must respect all religions! But we must also respect human life!! Killing in the name of God is man's idea not God!!!! livingforlove #rebelheart.
