Jared Leto came to the climbing gym I worked at once he was just kinda a douche to the staff
Pink the singer (in 2004) was incredibly friendly in a natural down to earth way, considering she was on the height of her fame at the time.
She was also shorter than me (13 years old then) and smelled VERY fruity and waited patiently for my mom to figure out how to take a picture of us with her phone. Cool person.
I met Phyllis Smith (Phyllis from The Office) and she was a sweetheart.
I don’t think anyone one would be surprised that Jeff Goldblum is nice, but I can attest to it. I was an extra in a movie with him. When he arrived on the scene, some nasty film crew woman was screaming at us not to bother him or ask for his autograph (which none of us had done). He must have heard her, because he turned right around and came over to talk to us.
Tom Felton (Draco Malfoy in Harry Potter) was very sweet, met him at Comic Con one year, he told me I had a beautiful smile 🙂
