Madonna‘s perfectionism is posing problems for her organizers.

The heartthrob singer is reportedly throwing tantrums while the rehearsals of her opening-night concert at the Great Western Forum in California are on.

“She’s being difficult in rehearsals. She’s a perfectionist and she’s bitching. Mostly she’s never satisfied with the way the dancers are dancing,” a source was quoted by Star as saying.

Despite her frequent outbursts and walkout from the rehearsals, the show promises to be a treat for fans.

The “show will be incredible”, the source added.

An array of stars including Tom Hanks, Jennifer Aniston, Ashton Kutcher and Demi Moore are expected to make an appearance at the show.
