Patrick Schwarzenegger has been living alone in his family's $23 million Brentwood mansion since news broke of his father Arnold's love child with the family's housekeeper.

X17online can report exclusively, the 17-year-old has ditched the tony digs and moved to smaller accommodations -- he's now living in a rented apartment! He's believed to have roommates, but the high-schooler is basically on his own. He's still in Brentwood, though further down the mountain in a more commercial part of town popular with recent UCLA graduates.

Last week, we spotted Patrick visiting his mom at a Beverly Hills hotel where she's believed to be staying. Meanwhile, Arnold's been holed up at the family vacation home in Sun Valley, Idaho, leaving Patrick alone in their 7-bedroom, 14,500-square-foot Brentwood estate. Apparently the house got lonely so Patrick moved to a more reasonably-sized place closer to his $25,000/year private school.

Still, through it all, Patrick seems to be handling things well -- making it to school on time every day and studying hard (check out the algebra text book in his hand).
