Beyoncé, Jay-Z row at Barack Obama gig

Beyoncé Knowles fell out with Jay-Z after he made a joke about her music at an election rally for presidential candidate Barack Obama.

The R&B diva was reportedly upset after Jay-Z stopped playing her single 'Crazy In Love' midway through, during his DJ set at the event in LA's Hollywood Bowl.

Earlier, the rap star, who headlines this year's Glastonbury Festival, attacked current US President George W Bush.

After turning off Beyoncé's record, Jay-Z told the crowd: "F*** that. Sorry Bey but f*** that - let's play something else."

A source told The Mirror: "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. Like any good husband would, Jay-Z grovelled and tried to get out of it with compliments."

They added: "It's a shame because earlier the pair had been flashing their tattooed wedding ring fingers. Both have 'IV' - the date of their wedding - inked on."

Jay-Z reportedly married the former Destiny's Child singer at his New York home on Friday, April 4. Neither artist has confirmed the wedding.
