Madonna, 65, has stirred social media with a series of topless selfies featuring a much younger, unidentified man. Captioned 'Hot Fun in The Summer Time,' her Instagram post shows the pop icon in various intimate poses, notably with the man sitting closely behind her. This mystery companion has been appearing in her social media posts since July, sparking speculation about their relationship. The photos come shortly after her breakup with 30-year-old boxing coach Josh Popper, following a year-long romance. Madonna, known for dating younger men, previously stated that her adventurous lifestyle and single motherhood naturally attract younger suitors. Fans have noted that the singer continues to look stunning with age, as she reflects on her miraculous recovery from a life-threatening illness last year.
