Madonna Boots Gym Class From New York's Reebok Sports Club

Madonna reportedly ordered a gym class to leave because she wanted to practice yoga on her own.

The 'Hung Up' singer went to New York's Reebok Sports Club on Saturday morning for the weekly class.

However, halfway through the lesson, the pop superstar allegedly asked the instructor and the other 25 members to leave as she wanted to exercise in private.

One member said: "When Madonna started talking to the instructor and he told her talking wasn't allowed, she replied, 'I need to speak to you,' and then said to the class, 'I want you all to leave.'"

The teacher soon left with the students and Madonna continued with her yoga.

When a dance class came in at 10.30 am dance, she still refused to leave.

A representative for Madonna said: "That sounds unlikely."Last month, Madonna outraged animal rights groups by dyeing her pet sheep different colours for a photo shoot.

The 49-year-old star and her director husband Guy Ritchie were branded "irresponsible" after colouring their sheep blue, pink, yellow and green for a Vogue spread at their English country estate in Wiltshire.

A spokesman for the Royal Society for the Prevention of Cruelty to Animals (RSPCA) said: "Why is it necessary and what are they trying to prove? It is an irresponsible publicity stunt."
