Did Jesse McCartney help invent Facebook?

When I saw The Social Network, I became obsessed with learning everything about Facebook founder Mark Zuckerberg. In one of my google searches, I learned that he went to Ardsley High School just like Jesse McCartney. So of course, the next time I saw Jesse, I had to ask if he was friends with Mark. "I didn't know him very well, but we're the two guys who came out of there with something to talk about," Jesse said. So the singer may not have had any part in creating Facebook, but he did see the movie twice and even recited some of the lines to me!
