Patrick Schwarzenegger graduates business school

Arnold Schwarzenegger's model and actor son Patrick is officially a businessman after completing his studies at the University of Southern California.

Miley Cyrus' ex graduated from the Marshall School of Business at USC last week (ends13May16) and took to social media to celebrate.

"I went to college for four years... #Fighton," he captioned a photo of himself with fellow graduates.

His proud dad also hit Instagram to praise the 22-year-old, writing: "Patrick, I’m so proud of you. You have grown into a great man - physically and mentally - and I can’t wait to see what you do next. Congratulations. I love you."

Patrick might have a ready-made top business job as his dad's right-hand man on the new season of TV show Celebrity Apprentice - Arnie has signed on to replace Donald Trump as the show's frontman.

Trump was joined by his kids on the show.
