Tequila-swigging Madonna has second onstage meltdown over Rocco custody battle as she brands ex-husband Guy Ritchie 'a son of a b***h' and begs 'someone please f*** me'

Swigging tequila from a fan's hip flask (right), Madonna suffered another onstage meltdown yesterday as she branded ex-husband Guy Ritchie a 'son of a b***h' and begged 'someone please f*** me'. The 57-year-old singer, locked in a bitter custody dispute with Guy over their son Rocco (together inset), couldn't contain her emotions during a second mumbling show in Melbourne, Australia. Her 'chaotic' appearance at the Rod Laver Arena included an emotional plea to the crowd, begging, 'Somebody take care of me please. Who is going to take care of me?' After falling off a tricycle (left), she told her fans she had 'messed up' her songs, before joking: 'You would think it was in my DNA.'
