Sienna Miller has apologised for her outburst at a bar in Pittsburgh last month and blamed it on tiredness.

Coming just days after Sienna was quoted as calling the city “Sh*tsburgh” in an interview, Sienna initially denied the angry exchange when she ignored a doorman’s repeated request for ID but the doorman and bar’s owner stood by their claims that she had yelled “I am Sienna Miller. I am a famous actress!” as she was asked to leave.

She has now said: “I’m very sorry about being rude but I was working so hard on the movie The Mysteries Of Pittsburgh. I was really tired and it came out wrong. I feel terrible about it.”
