Singer Amy Winehouse is facing a police investigation for allegedly lashing out at a theatre manager after subjecting panto actors to a stream of abuse.
The troubled star is said to have disrupted a performance of Cinderella on Saturday night by heckling the cast.
She is later alleged to have launched a physical attack on a member of staff at the theatre in Milton Keynes, Bucks.
The Back to Black singer was said to have shocked children and parents by shouting abusive language.
Refusing to sit down, she also branded the Ugly Sisters "b******", The Sun reported.
According to the paper, she later launched herself at front-of-house manager, Richard Pound, allegedly pulling his hair, punching him and kicking him between the legs.
Her outburst was said to have exasperated stars of the show, including Fairy Godmother Anthea Turner, comedian Bobby Davro, playing Buttons, and actor Mickey Rooney, as Baron Hardup.
A spokesman for Thames Valley Police said: "At around 9.05pm on Saturday night officers were called to Milton Keynes Theatre in Marlborough Gate following reports that a 27-year-old man had been assaulted."
"No arrests have been made and the incident is being investigated."
