The Pineapple Express actor who is studying for a Master of Fine Arts in Writing at the college is finding it hard to walk around as there are always hoards of eager girls trying to catch a glimpse of him.
A source said: “Now that girls have figured out his schedule, every week there's a bigger crowd outside his lectures waiting just to see him leave. It's getting to be that there are so many people, it's embarrassing.”
A university representative refused to comment on reports extra security teams will now be posted outside the actor’s classes.
The spokesman said: “We don't comment on matters of pop culture.”
The 30-year-old actor graduated with a degree in English from the University of California, Los Angeles, last year.
He then moved to New York to study at Columbia and at New York University’s Tisch School of the Arts, where he takes filmmaking classes.
