The former Black-ish actor, 51, earned his diploma from Howard University in Washington D.C. on Saturday. Anderson celebrated the exciting moment on Sunday with an Instagram post, in which he called his graduation "a full circle moment" that was "30 years in the making." He also shared several photos from the big day, including one with fellow actor and Howard grad, Taraji P. Henson, who delivered the commencement address at the ceremony, and Phylicia Rashad, the current Dean of Howard University's Chadwick A. Boseman College of Fine Arts. "To quote Biggie, 'IT WAS ALL A DREAM!'" Anderson began his post. "Words can't begin to describe the emotional roller coaster [sic] I'm on right now. It's literally been 30 years in the making."
