Reese Witherspoon visits her old college dorm room

Reese Witherspoon was in her alma mater, Stanford University, as a guest speaker and the actress also visited her old dorm room.

The 41-year-old star hung out with its current resident, a student named Caitlyn.

"Surprise! While re-visiting @Stanford, I popped by my old dorm room.... And met its newest tenant, Caitlyn!" Witherspoon wrote on Instagram alongside a photo of her and the student inside the room.

The photo also shows another student in a dorm room opposite Caitlyn's, typing away at their computer, seemingly unaware of the actress' presence.

Witherspoon attended the university in the '90s as an English Literature major but never graduated, opting to concentrate on an acting career.
