Madonna is said to be the richest woman in showbusiness, but she knows how to take care of the pennies.

This week, the Queen of Pop, 53, visited Osteria Cotta in New York, with her boyfriend, Brahim Zaibat, 24. Fellow diners were surprised when she “brought her own red wine in a bag, along with two beautiful crystal glasses”.

One claims: “They poured the wine and immediately put the bottle back in the bag, so nobody could see what it was. At the end, they took the empty wine bottle and the glasses with them.”

Zaibat, a dancer, incidentally, picked up the bill, paying with his credit card. Madonna is known to drink only Kabbalah water, which costs £6 a bottle, as it has been blessed.
