Madonna details recent phone call she had with Britney Spears

Queen of Pop previously called singer's conservatorship a 'violation of human rights'

Madonna is offering her support to Britney Spears.

The Queen of Pop hit the red carpet on Thursday night for the New York City premiere of her new documentary "Madame X" where she shared that she's been keeping in touch with Spears.

Spears, whose conservatorship battle against her father Jamie has been a hot button issue for months, apparently received a phone call from the "Like a Prayer" singer earlier in the day.

Reflecting on the conversation with her pal, Madonna told Entertainment Tonight she was "just checking in on her, and congratulating her on her marriage. Or her pending marriage."

Earlier this month, Spears announced her engagement to model and actor Sam Asghari, who she's dated for over four years.

Meanwhile, the pop star has been fighting to be freed from the conservatorship she's been under for 13 years. Over the summer the "Toxic" singer accused her father of "conservatorship abuse."

In July, Madonna appeared to confirm she's a supporter of the #FreeBritney movement. She spoke out in support on social media while sharing a throwback photo of herself wearing a t-shirt with Spears' name on it.

"Give this woman her life back," Madonna demanded in writing over the photo. "Slavery was abolished so long ago!"
