Sienna Miller has apparently claimed she has a mild case of Tourette's Syndrome.

The film star, admitting she can’t stop “putting a foot in it”, put her tendency to cause upset with swearing and insults down to the condition.

Among recent slip-ups, she told The Sun, was renaming Pittsburgh “S***sburgh” while filming in the US city.

“These things just come out of my mouth," she told the paper. “I’ll say the most inappropriate things, guaranteed... but I don’t deliberately hurt anybody.”
