DID CIARA & KERRI HILSON HAVE A CAT FIGHT AT THE POWER LIVE CONCERT?

Did Ciara and Keri Hilson go at it during Sunday’s Power Live concert at Governors Island?
Insiders initially told us that the two R&B/hip-hop artists, who've had a long-brewing feud through their songs, had a verbal catfight backstage that kept Hilson from performing.

The sources, however, suddenly changed their stories after the singers’ publicists got involved. The reps' stories, which are both slightly different, contend that Hilson was not even at the event.

Relations have been tense between the two women ever since Hilson released a remix of her song "Turnin' Me On" that reportedly dissed both Ciara and Beyonce, even though Hilson downplayed rumors of a beef.

Ciara then fired back with "Basic Instinct (U Got Me)," though she also sidestepped reports that she and Hilson, who has written songs for her, were warring.

Still, both women were supposed to perform at the show. A schedule sent to us by the publicity firm handling the event indicates that Hilson was supposed to go on from 8:55 to 9:15 p.m. Ciara was slotted for the more prestigious 10:05 to 10:35.
