We reported that Minogue started her X2008 concert extravaganza in the world's romance capital on Tuesday night, but it seems only after overcoming a string of problems.
There were also technical problems with giant video panels and with using the massive stage floor as another screen.
"Considering Kylie couldn't sing on Friday and the problems with the stage on Monday night, it's a miracle the show happened at all," an unnamed source close to the singer told the paper.
The newspaper said some of Kylie's team were also concerned that the show, which cost £10 million ($25 million) to produce, is too long and that the star has not included enough of her chart hits.
Minogue performs 28 songs and makes at least seven costume changes in outfits designed by France's Jean Paul Gaultier. The show will go to Britain next month.
