The unnamed female, who bears a striking resemblance to Hudson, was photographed by snappers who were convinced she was the real one, reported Contactmusic.
Now Hudson has taken to her Twitter to clear the air about her lookalike, insisting she feels sorry that she had to deal with photographers.
"Cute girl! But that ain't me! I know the poor girl was like, 'Why are they taking pictures of me!!' Wow!," posted on Twitter.
