Rita Ora was gutted as one of her closest friends was revealed as Firework on The Masked Singer - after missing one huge clue.
Actress Jaime Winstone - daughter of renowned hard man actor Ray Winstone - was unmasked as the colourful contestant.
She was surprised that Rita never realised it was her, especially because of one obvious hint to her bestie, Birmingham Live reports.
So stunned she fell off her chair, the pop star was left with her head hanging on the desk, annoyed for second-guessing herself after thinking it was Jaime in an earlier episode of the hit ITV show.
She ranted: "I said your name and I'm so mad I didn't keep it,"
Host Joel Dommet then rubbed salt into the wounds, asking: "Rita you're like best friends right?"
"She is," Rita replied, before admitting: "Firework...we all call her that."
Rita had actually though her friend was Birmingham Superstar singer Jamelia.
Asked why she had taken part in the show, Jaime, who is best kown for playing Becky in film Kidulthood and for her told in Sky1 sitcom After Hours, said: "For me it was a no brainer - for my son, he's five hyears old."
She then gave him an adorable shout-out, gushing: "Raymond I love you, Mummy's a firework!"
None of the panelists had managed to uncover Jaime's identitiy - and their guesses were wildly off the mark.
Mo Gilligan had guessed it was Dani Dyer, Davina McCall plumped for Jennifer Lawrence, Jonathan Ross thought it was Danny Dyer and Olly Alexander said he thought it was Derry Girls' Nicola Coughlan.
Jaime was the bookies favourite to be revealed as Firework.
Ladbrookes odds before the show had the actress at 3/1, with Pixie Lott behind at 7/2 and Michelle Keegan in 8/1.
