JAMIE FOXX has upset Rihanna by embarrassing her in front of revellers at a Las Vegas nightclub.
The Ray actor was cracking jokes for fellow party-goers at Sin City's Tao hotspot when he spotted the R&B star and repeatedly asked her to join him on stage and take the microphone.
according to New York Post gossip column PageSix, she refused, and Foxx got the DJ to blast out her hit Umbrella over the speakers.
When he saw that she was about to leave, he ordered her to stay which reportedly leaving her "fuming".
A source told the paper: "Jamie took over the microphone and started doing a show. Halfway through, he asked Rihanna to join him onstage. Rihanna declined, but Foxx continued to badger her."
When the DJ began to play Umbrella, the source adds: "That was the last straw. She got up to leave, and Jamie told the DJ to stop the record. (He shouted) 'You can't go while your song is playing. Relax.'
"Rihanna stayed and pretended to enjoy herself, but it was so obvious she was fuming. As soon as the song was over, she got the hell out of there."
Foxx sparked outrage in April (09) during a U.S. radio interview when he urged 16-year-old Hannah Montana star Miley Cyrus to take heroin and make a sex tape.
