"MADONNA SE DESMAYA DOS VECES, EN UN CONCIERTO EN BULGARIA". "¿CANSANCIO, HASTIO O CANSANCIO DEL TRABAJO?". "¿HA TENIDO ALGO QUE VER JESÚS?".

"IT'S no secret MADONNA, has a fitness

regime that would make a

Royal Marine weep".

"But after collapsing on stage TWICE during Saturday's Sticky & Sweet show in Sofia, Bulgaria, it might be time to take her foot off the gas".

"Madge lost consciousness singing Holiday and had to be held up by a dancer. To see more pictures of Madonna check out our slideshow, below".

"Then, as she left the stage during Spanish Lesson, she passed out and fell over. A source said: "Madge was really worried backstage. She had to sit down for a longer break than usual between songs".

"She refused to end the show or take a break after the Holiday dizzy spell. It turns out she's suffering from exhaustion. She is anaemic. She was advised to postpone the last two shows in Israel for a few days, but logistics and stubborness stopped her. She'll do them then take some rest".
