Celebrities I Am Not Sure I Actually Saw or F It Was Just a Lookalike

I'm A Dane living in Spain so it's not that often I get the chance to spot American celebrities. I have seen lots of Danish celebrities though, but I won't include them in this list...
  1. When I was 12 my family and I went to the US on vacation. We saw someone looking a lot like Lance Armstrong in an airport ( I think somewhere in the Midwest). We went to get a napkin to ask for his autograph and he had left when we came back and I never found out if it was really him.
  2. Sahara Jolie Pitt
    I saw a girl on the street in Valencia,Spain that really looked like her - she was walking with a white woman and they were speaking American English. I wonder if it was her nanny, btw - don't Brad and Angelina have a house in Spain?
