Miley Cyrus has worked with Marc Jacobs in the past to raise funds for Planned Parenthood with a portrait series shot by artist Marilyn Winter. The 50 limited edition prints were sold for $5,500 on Artsy, all proceeds went to the organisation. The outtakes from the shoot were then printed on t-shirts and up for sale by Marc Jacobs.

Cyrus spoke out against recent restrictive anti-abortion laws that have passed in a number of US states including Georgia, Alabama and Ohio, posting on her Instagram story that "No man should make laws regarding women's bodies."

The former Disney star's new EP, She Is Coming is out now.
