Madonna is being blazed by criticisms after she shocked concertgoers at Brisbane’s Entertainment Centre. It is being said that The Material Girl had crossed the line on Thursday, when she pulled the woman’s top down.

Madonna exposed the breast of a female fan, who she had invited onto the stage in Brisbane. She jokingly branded the whole act to be “sexual harassment.”

According to entertainment reporter Peter Ford, this incident could be potentially serious.

“Legal advice given to me. Unless it was all agreed upon in advance Madonna did indecently assault the woman last night,” he said.

“[She] exposed the woman’s bare breast. Technically that is indecent assault. I don’t know that she intended to do that – she may have thought there was a bra underneath, or something.”

Ford drew out “Madonna’s on-stage victim.” However, the girl was “thrilled and proud” to have had her breast exposed by her idol last night, says The West Australian.

Ford said that the pop star got out girl out of the audience and they were having fun. This something she usually performs on stage.

Many people are questioning whether the singer’s recent legal anguish over her son’s custody, made her act in that manner.

While calling it a “meltdown,” UK commentator Piers Morgan had asked the veteran pop star to cancel her Rebel Heart tour.

“Madonna is in total meltdown. She needs to cancel this tour asap,” he said on Friday.

Madonna and her ex-husband Guy Ritchie are going through a custody battle over their 15-year-old son Rocco. According to a source, this legal problem has allegedly left her on the threshold of a “stress-induced meltdown.”

According to a concertgoer, Richard Stevenson, Madonna is probably becoming mentally unstable.

Madonna is known to enter late on stage, but on Thursday night she was just 20 minutes late, says The Australian.

Madonna is supposed to perform at Allphones Arena in Sydney on Saturday and Sunday night, finishing her world tour.
