"Hills" star Spencer Pratt graduated from the University of Southern California after 10 years and now he has the official degree to prove it.

Pratt tweeted in December "Today was my last day of College @USC! Best 10 years of my life! #Trojans."

He finished 10 years after he enrolled. His stint on "The Hills" opposite wife Heidi Montag slowed his graduation.

Pratt posted a picture Thursday of his diploma with the caption, "The life changing piece of paper! #USC #Trojans #alumni #FightOn."
