Beyonce Knowles had a furious row with husband Jay-Z over one of her biggest
hit singles.

Beyonce, who is believed to have married the hip-hop mogul earlier this
month, reportedly lost her temper at a concert when Jay-Z told the DJ to
stop playing 'Crazy in Love' - a track which also features the rapper.

Jay-Z allegedly said: "F**k that. Sorry Beyonce but f**k that, lets play
something else."

The concert, which was held at Los Angeles' Hollywood Bowl, was organized in
support of US Presidential candidate Barack Obama.

A source told Britain's Daily Mirror newspaper: "Beyonce had been side stage
for most of the night, dancing and singing along. Jay-Z meant it as a joke
but she didn't see it that way. After he came off stage, she confronted him,
demanding to know what the hell his comments had been about. She was
gesturing wildly and not looking happy.

"Later, peace was restored and they were smiling and looking happy again."
