The hot-tempered Russian was said to have thrown "a hissy fit" after the chart- topping stars locked themselves away in a private room for ten minutes.

Kylie and Enrique were said to be going through their lines before presenting the Best R&B act at the awards show in New York. But a source behind the scenes at Radio City Music Hall said Enrique seemed "blown away" by the diminutive Aussie and begged for her number.

The insider said: "Anna hit the roof, she threw the mother of all hissy fits and totally wiped the floor with Enrique.

"Kylie is stunning and Enrique kept glancing over at her. Anna's attractive, but she gets very jealous.

"It's bad enough when fans come onto him but trying to compete with one of the world's most beautiful women is another matter.

"Kylie was quite flirty with him but she's a professional and to be honest, she didn't act like she fancied him. But that probably made him like her all the more."

Kylie, 34, may be in the market for a new boyfriend when she return to Britain. Her on- off love James Gooding has been spotted out on the town with former Hollyoaks star Davinia Taylor.

James an Kylie enjoyed a holiday together in Bali just two weeks ago, but James was spotted at Davinia's home in London's Belsize Park, three nights in a row last week.
