The University of Southern California just added another famous face to its student body.
As of Tuesday, Arnold Schwarzenegger and Maria Shriver's son Patrick Schwarzenegger, 18, appeared to be all moved in to his dorm at the popular L.A.-based college.
"It's very different moving boys into college compared to two girls," Shriver, 56, Tweeted, along with a photo
, from her son's new living space, which happens to be the same room her daughter Katherine Schwarzenegger lived in when she attended the school. "So much less stuff. No matching this and that."
A day later, Shriver's words seemed a little bit tougher to type.
"Sent my third kid off to college today," she wrote
. "Heart-wrenching for me, so exciting for him. I understand how blessed he is."
Katherine also lent a hand in helping her little bro get settled.
"So exhausted from moving @PSchwarzenegger into my old dorm at USC!!" she Tweeted on Tuesday
. "So freaky and I'm for sure going to be waterworks all day tomorrow!"
As for the student-to-be, it appears he's still adjusting to his latest living quarters.
"It's a little stressful but I'm so excited to be moved in," he Tweeted on Wednesday
in response to an inquiring pal.
A day later, he wrote
, "10000000000 degrees in my dorm!!! Can't sleep at all."
