Posing for a selfie in the sunshine, Spencer shared his excitement with fans on Instagram.
He commented: "@USCEDU #USC #GRADUATION #Dornsife #betterLateThanNever #PoliticalScience #tenYearMission #NoMoreTests #SchoolsOUTforever."
Spencer's wife and former Hills co-star Heidi Montag was first to wish him a massive congratulations: "@spencerpratt Congratulations!!!! You did it!!!! #2014USCGraduate #SoProudOfYou!!" she tweeted.
Spencer, 30, first found fame alongside Brody Jenner in MTV show The Princes Of Malibu before landing a role in the hugely successful US reality series The Hills in 2006. It was there that he met Heidi, now 27, and the couple married in 2009.
The reality star, who appeared in CBB with Heidi last year, began his degree the year before he appeared on telly for the first time and has been dipping in and out ever since. He completed his studies in December 2013 and has now finally graduated.
