Rap superstar 50 Cent kicked Paris Hilton offstage and reduced her to tears during a pre-Super Bowl concert on Thursday.
Hilton hosted the bash for 944 magazine in Scottsdale, Arizona and was stunned when the headliner turned on her.
The two star attractions have been romantically linked in the past, but there was no love lost when Hilton tried to steal the show.
After 50 Cent namechecked her during his performance, Hilton climbed onstage to dance, but was promptly told to "Get the f**k off the stage" by the angry star.
Onlookers tell PageSix.com the outburst prompted Hilton to break down in tears, which was captured on film by photographers at the event.
The party was one of a number of bashes taking place in Arizona this weekend to mark the Super Bowl showdown between the New England Patriots and the New York Giants on Sunday (03Feb08).
