Miley Cyrus Snags a Kennedy, Sorta ... Patrick Schwarzenegger

Miley Cyrus is officially Kennedy adjacent ... she has formed a perfect union with Patrick Schwarzenegger, famous for his good looks, his father and his Shriver lineage.

Patrick -- a USC student -- took Miley to a USC football game at the L.A. Coliseum, and they clearly wanted everyone to know they're together.

It was pretty obvious earlier in the week, when they went to a Q&A for Maria Shriver's new movie together ... when you hang with the guy's mom, you're definitely banging.

The Cyrus clan in Hyannis Port will be epic.
