Celebrities In High School: 5 Stars Who Graduated In 2012!

The class of 2012 has seen some pretty amazing graduates: David Boone , a homeless teen in Cleveland who will attend Harvard next year; World War II veteran Jack Fletcher , who received his diploma at age 86; and Senait Weldermariam , who became the first person in her family to enroll in college, to name a few.

And some graduating seniors have balanced their studies on top of a nearly full-time job as an actor or singer. Last year, Hollywood's class of 2011 included Dakota Fanning and Miranda Cosgrove, and this year, Ariana Grande and Justin Bieber are among the a-listers who donned a cap and gown and received their diplomas.
