It looks like Britney Spears has taken a leaf out of Mariah Carey’s diva handbook.

The troubled singer angered fellow gym goers after she kicked them out of a room she wanted to work out in.

Britney wanted to work up a sweat in private at Bally gym in Los Angeles in her bid to whip back into shape.

But when Brit arrived for her private sesh, an aerobics class was already in session after one muppet at the gym doubled booked the space.
