Now a 45-year-old businessman, Jimmy is to make his West End debut in hit musical Grease early next year.

The youngest member of the Osmond clan will star as Teen Angel – played by Frankie Avalon in the film – at the Piccadilly Theatre from January 19 to March 14 next year.

Jimmy, who finished in fourth place in I’m a Celebrity... Get Me Out Of Here! in 2005, gushes: “It’s been a lifelong dream of mine to play in the West End and what better show than Grease?

"It is fast, fun, energetic and full of talent and I am thrilled.”
