When you meet someone you are very fond of, like a celebrity,
movie star, etc. and you get completely overwhelmed,
paralyzed and/or
speechless by the experience.
I've just bumped into
Scarlett Johansson tits at Starbucks. I'm still starstruck!
I got really starstruck when I saw
George Michael on that public toilet.
Mr
George Lucas made a surprise appereance at the Star Wars Convention last night. We all screamed. Everybody was soooo starstruck!
