Mariah Carey fails to stand for JLo

Mariah Carey failed to give Jennifer Lopez a standing ovation when she performed on American Idol last night.

The renowned diva sits on this year's judging panel alongside Randy Jackson, Keith Urban and Nicki Minaj.

Former Idol judge Jennifer gave a show-stopping performance of her new single Live it Up, which features Pitbull for the season finale last night. The beauty writhed around on stage, scantily clad in a white mini dress after the rapper opened the show.

Despite her energetic performance, Mariah stayed squarely on her chair while all three of her fellow judges jumped up to salute Jennifer's display.

Mariah was seen smiling in her chair, while the 43-year-old garnered rapturous applause.

There is famously history between the pair. The feud began shortly after Jennifer launched her recording career and was linked to Mariah's ex, Sony chief Tommy Mottola.

When asked about collaborating with Jennifer, Mariah once claimed: "I'd rather be on stage with a pig. A duet with Jennifer Lopez and me just ain't gonna happen."

Mariah apparently also insisted on $2 million more than Jennifer when she took over her seat on Idol this season.

Despite her demands, rumours are circulating that producers are planning to replace the Mariah with Jennifer in a bid to save floundering ratings.

When questioned about the validity of the hearsay recently, Jennifer was evasive.

"Um, you know, I don't have much to say about that right now," she said. "I don't know… it's too far off to say right now."
Meanwhile, Mariah showed off her vocal range during the show's finale last night. The star wowed with a seven-minute medley of some of her biggest hits, including Vision of Love and Hero, before ending with her newest single #Beautiful.
Jennifer Hudson also returned to the Idol stage to sing Inseparable with finalist Candice Glover.
