Grease Is The Word judge, Sinitta, will have the benefit of two bulky bodyguards on the ITV TV show tonight as she wears a £250,000 necklace.

Sinitta will be wearing the diamond and platinum necklace on behalf of charity Caudwell Children who will be auctioning it off later this month.

An insider said: “Because of safety fears producers have hired two bodyguards.

“They are under instructions to stay by her side all night to ensure that the necklace does not go missing.”
