Madonna, 65, flexes her muscles in skimpy negligee as she returns to stage after getting SUED by fans accusing her of ‘false advertising’ for performing ‘two hours late’

Madonna donned a dodgy wig and flexed her muscles while wearing a skimpy red négligée during her sold-out Madison Square Garden concert in Manhattan on Monday – five days after two fans sued her for ‘false advertising.’

The 65-year-old Queen of Pop wore the scantily-clad costume to sing happy  birthday to her daughter Chifundo ‘Mercy’ James Kambewa Ciccone, who turned 18 on Monday.

While on tour, Michigan-born Madge has Mercy accompany her on piano for her 1992 track Bad Girl and her 18-year-old son David Banda Mwale Ciccone accompanies her on guitar for her 2003 track Mother and Father.

Last Wednesday, Michael Fellows and Jonathan Hadden filed a federal civil lawsuit in the Eastern District of New York seeking unspecified damages from the seven-time Grammy winner for going on ‘two hours late’ during her December 13 concert at Brooklyn’s Barclays Center.

‘Sound check issues’ caused Madonna to go on at 10:45pm rather than her usual call time between 9pm-10pm that particular evening – according to People.
