I have met several famous people because my mom works at drivers license and even famous people need to go to the DMV
Here are some people I have met:
John Travolta and Kelly Preston
Ricky Martin
Gloria Estafan
Lots of small screen novella actors ( They are all really cute

)
Shaq
Alonzo Mourning
Lots of basketball and baseball players
Usher (At and autograph signing)
Shakira
Robin Gibb (He still sends my mom a christmas card every year)
Clay Aiken (After seeing spam alot in nyc he came out)
Willy Chirino
Those are all I recall off the top of my head there are probably some more.
It's surprising but the nicest celebrity was Ricky Martin. He was an absolute sweetheart. He even went to the back and let us take all the pictures we wanted.
