X Factor judge Dannii Minogue has apparently negotiated a half a million pound pay rise.

The Australian pop singer – who was widely reported to have clashed with fellow judge Sharon Osbourne on the last series – has had her salary almost doubled by TV bosses, according to reports in The Mirror.

A source said: “Dannii is thrilled to be back. She’s not concerned about the oestrogen battle between herself and Sharon – she’s a big girl.

“There may be tension between herself, Louis (Walsh) and Sharon but all three judges realise it’s this electric chemistry that has given the show an edge.

“The pay rise, taking her from around £400,000 per series to £900,000, is well-deserved. Her act won the whole competition for starters, and ratings for the series were fantastic.

“And this year it looks like there’ll be two shows a week – one on Saturday and one on Sunday night, so in effect she’s doubling her hours.”

The source said Dannii has also been linked to American Idol “but is still in the negotiating stages – nothing’s been confirmed”.
