So starstruck when bumping to the actor on the red carpet that Watson lost words and got 'really giggly'.
"Harry Potter" star Emma Watson was left red-faced when she met Matt Damon - because the actress was so starstruck she "literally couldn't speak". The 20 year old, who found fame as a child in the Harry Potter franchise, often meets acting icons on the red carpet and at award ceremonies.
Watson admits her encounter with Damon was a highlight for her - but she found herself lost for words when she came face-to-face with the "Invictus" star. She tells Britain's Celebs on Sunday magazine, "It's always the weirdest people, like I got really starstruck when I met Matt Damon. I literally couldn't speak, I went bright red."
"You go to these events, and even if you've never met the other person before, they're like, 'Can we get a picture of you two together?' I'm like, 'I don't even know who this person is!' So they push you into a photo together. I just get really giggly and embarrassed. He so knew I was really embarrassed."
