The "Like a Virgin" singer took to Instagram Story to post a throwback photo of herself wearing a Britney shirt. She also expressed how she feels about Britney's conservatorship.
"Give this woman her life back. Slavery was abolished so long ago! Death to the greedy patriarchy that has been doing this to women for centuries," Madonna wrote. "This is a violation of human rights! Britney we coming to get you out of jail!"
Madonna's been a Britney supporter for decades. In 2000, she also rocked another Britney tee during one of her concerts.
The pop icon also collaborated with Britney on the 2003 hit "Me Against the Music." They also shared a steamy kiss during their 2003 MTV Video Music Awards performance with Christina Aguilera. Additionally in Britney's 2008 documentary For the Record, Madonna expressed that she felt "maternal" towards the "Stronger" singer.
"There's a certain fragility about her and vulnerability about her that makes me feel maternal towards her," Madonna stated. "There are aspects about her that I recognize in myself when I first started out in my career. I also admire her talent as an artist."
