Patrick Schwarzenegger: Meet My Smokin' Hot New Girlfriend

Patrick Schwarzenegger is moving on from Miley Cyrus nearly a year after their split -- and his new chick is younger, blonder and more Southern than his ex.

TMZ has learned Schwarzenegger just bagged a hot Alabama native named Abby Champion.

Sources close to the pair tell us the relationship is super new -- but 22-year-old Patrick's clearly ready to get couple-y with this one ... the two were spotted running errands together on Abby's birthday.

Champion's signed to Next models and turned 19 on Sunday.

Good job, Patrick. Dad must be proud.
