Madonna's been a mess since son Rocco moved in with his dad, Guy Ritchie, in December.
But as her custody battle over the 15-year-old rages on with the director, it's been revealed that she's not the only one who's heartbroken without Rocco around.
According to Britain's The Mirror, Madge and Guy's 11-year-old adopted son David Banda is pining for his older brother too.
"Everybody is talking about Madge and Guy's fight over Rocco -- but there's much more to it," a source told the Mirror.
"The dispute is hard on the whole family, and David is really feeling it."
Madonna and Guy's youngest son "very much looked up to Rocco in that big brother role," the source explained.
"But they rarely see each other now, and the longer this continues, the more upsetting that will become for him," the source added.
As she and Guy continue to duke it out in court in both New York City and London, Madonna been making headlines for her spiraling behavior.
While performing on stage in Melbourne during the Australian leg of her Rebel Heart Tour this weekend, she had what many media outlets are calling a "meltdown" in the middle of her March 13 concert.
She not only fell off a tricycle and told fans she'd "messed up" her songs, but begged for sex and swigged tequila from a fan's flask before pleading, "Somebody take care of me, please. Who is going to take care of me?" reports Britain's The Sun and Daily Mail newspapers as well as the MailOnline.
She also reportedly told the crowd, "If I have learned one thing in my life, it's just to go with it. If you just laugh it doesn't hurt as much."
Madonna also dedicated a song to her estranged son and had one of his childhood photos projected on stage -- something she also did a week earlier as she and Guy prepared to head to court again.
"Being cut out of Rocco's life has hit Madonna hard and it's clear she blames Guy," a source told The Sun.
On March 13, The Mail On Sunday also alleged that Guy's lawyers have asked Madonna to pay for the director's legal fees in the fight over Rocco -- and that Madge is "outraged" over the demand.
"It's a lawsuit Guy instigated and now wants Madonna to pay," a source told The Mail On Sunday. "Madonna says she gave him [$72 million dollars] and an estate in Wiltshire when they divorced and she thinks that is quite enough. She can't believe he is cheeky enough to ask her for the money."
