Cheryl Cole finally landed her longed-for role as a judge on the US version of The X Factor today and declared: "I can't wait to get started."
But the 27-year-old's new job means she will leave the British version of the show after three years.
Today's announcement by Simon Cowell and bosses of the Fox network ends months of speculation about whether Cheryl could make it in the US.
Launching the show with her pal Simon could make the erstwhile Girls Aloud singer a huge star, but there had been fears her accent could be impenetrable for American viewers. Cheryl will take her place on the panel alongside show boss Cowell, respected former record boss LA Reid and one more unnamed figure when the show starts later this year.
Simon said: "I'm thrilled for Cheryl. She is massively excited about this show, and has been fantastic to work with.
"She is also a complete brat. Most importantly, this girl can spot talent."
The appointment spells the end of her run on ITV's hugely successful Saturday night UK show. She has twice mentored the eventual winner during her stint.
ITV's official X Factor website confirmed she would be quitting the programme. It said: "It's with a pride-filled lump in our throat that today we announce Cheryl Cole's departure from the UK version of The X Factor."
Cheryl said: "I'm so excited to be taking part in the American version of The X Factor.
"I can't wait to get started. I just can't decide whether I am more excited to find and nurture the talent or for the unbelievable amount of amusement and entertainment I will have watching Simon doing everything and anything he can to beat me."
