Even celebrities had to start out somewhere, and for many stars that meant dealing with a roommate before fame came calling. But sometimes two budding stars found each other as roomies while waiting for their big breaks.

Justin Long once roomed with a co-star, but moved out of their California home when he realized they were acting "like an old married couple." Who was his roomie?

Long's roommate was his "Accepted" co-star Jonah Hill. Though still friends, in 2009 Long said he finally moved out because he was constantly nagging Hill to pick up after himself.
