Legendary musician Madonna well and truly got into the groove with her toyboy lover Josh Popper, 30, after inviting him to join her on stage in New York.

Mixing business with pleasure, Madonna turned up the heat with her younger boyfriend on the first US date of her epic Celebration tour. Romance was in the air at the Barclay Center, in Brooklyn, when Madonna planted a kiss on Popper’s cheek in front of the 14,000-strong crowd.
