Jennifer Lopez's husband had been acting like a thorn in the flesh during preparations for her latest fashion show, reported the New York Post.

"Marc Anthony was driving the production crew crazy," the daily quoted sources as saying.

The salsa-singing husband of J Lo "convinced her that all the music was wrong and had to be changed. He also decided the order of the outfits was wrong, and changed that too. He also didn't like the lighting".

The show was scheduled for Friday night, and Lopez has been without a manager since jettisoning of Benny Medina who had guided her to stardom.

"She doesn't need a manager because Marc is her manager," the source said.
