J1 students seem to have all the luck this year, bumping into celebs like it's nobody's business.

And it's not just any Z-list star either, they're actually quite big names.

First, we had one girl take a selfie with Scott Disick during the week, and now more Irish students are after running into Charlie Sheen.

Jessica Reilly took to Facebook to share a picture with the Two and a Half Men star and her friends.

"Bumped into this legend in an elevator yesterday, he was kind enough to hop into a photo and tell us to stay out of trouble," she captioned the pic.

Ah, those college days…
