I’m sure you all remember when Keri Hilson supposedly dissed Ciara in her “Turnin’ Me On” remix, and then backtracked and denied it, right? And then Ciara addressed it in “Basic Instinct (U Got Me).” Well apparently the ladies are at it again…the two were allegedly involved in a backstage fight at a New York concert over the weekend.

Keri was said to have refused to perform at the Power Live gig on Sunday because she was so upset after trading insults with the R&B singer. But the stars’ reps are downplaying the rumors, insisting Hilson was not even in attendance at the show.

Hilson’s publicist Sherlen Archibald tells the New York Daily News his client wasn’t in the Big Apple because she “had an emergency in L.A.” And Ciara’s spokesperson is adamant the story is “not true”, claiming Keri failed to turn up because she had “missed her plane”.
