Miley Cyrus and Patrick Schwarzenegger Go Public

The guessing game is over and the romance is on for Miley Cyrus and Patrick Schwarzenegger.

The 21-year-old pop star was practically plastered to the handsome son of Arnold Schwarzenegger and Maria Shriver during the USC Trojans game against the California Golden Bears on Thursday.

Miley and Patrick, who is also 21, provided entertaining distraction while making out in full view of spectators crowding the Los Angeles Memorial Coliseum.
