Patrick Schwarzenegger, 18, got help moving into his dorm room for his freshman year at the University of Southern California from his mom, Maria Shriver, 56, who took on the task in a sporty pair of leggings, t-shirt and sneakers. After Schwarzenegger was good and settled, mom and son relaxed in his new dorm room, tweeting a picture of them in his new furnished room.

This is just the latest in a long line of milestones in an eventful year for Schwarzenegger, who was just doing his first internship this time last year, attending the prom in May, recovering from a skiing accident this spring, and appearing shirtless in his own billboard for Hudson jeans last fall. You know, just a typical year in the life of a teen whose millionaire action hero-turned-governor dad was just outed for fathering his housekeeper's son.

Schwarzenegger, who was also briefly linked to country / pop superstar Taylor Swift, 22, who now appears to be getting serious with Schwarzenegger's cousin, Conor Kennedy, was also aided in his transition to college by his older sister, Katherine Schwarzenegger, 22, who had stayed in the very same dorm room that her younger bro was moving into during her education at USC, reports E!Online.

"So exhausted from moving @PSchwarzenegger into my old dorm at USC!!" Katherine tweeted. "So freaky and I'm for sure going to be waterworks all day tomorrow!"

Shriver also took to Twitter the next day, counting her blessings. "Sent my third kid off to college today … heart-wrenching for me, so exciting for him. I understand how blessed he is to be going and how blessed we are to be able to send him."
