Amid Britney's conservatorship battle, the La Isla Bonita singer has been providing her with moral support.
Madonna, 63, was at the premiere of her new documentary concert film, called Madame X, where she revealed she spoke to Britney earlier that same day.
Speaking to Entertainment Tonight, the singer said she was 'just checking in on her, and congratulating her on her marriage. Or her pending marriage.'
'I love her,' she added after.
Britney and Madonna collaborated on their song Me Against The Music in 2003.
