Patrick Schwarzenegger wasn't looking for during his spring break trip -- because he's already found it. The University of Southern California freshman was seen kissing his new girlfriend, classmate Tootsie Burns, as they swam in the Atlantic Ocean March 28.

The model and philanthropist showed off his buff, shirtless body in a plaid swimsuit, while his girlfriend rocked a black string bikini. "Wake, bake, Oreo banana shake," Patrick tweeted. The 19-year-old son of Arnold Schwarzenegger and Maria Shriver had previously revealed that he was in town for the Ultra Music Festival.

The paramours kicked off their spring break one week earlier with a trip to Cabo San Lucas, Mexico. Patrick shared several pictures from his getaway via Twitter and Instagram. "Cabo + St. Patty's day = too nuts," he told his followers March 17.

To get in shape for spring break, Patrick logged extra hours in the gym -- but he didn't feel the need to modify his diet. "Eating my Reese's peanut butter cups while drinking my peanut butter shake. Peanut butter heaven," he tweeted March 3.

When one of his followers suggested that his eating habits might cause him to gain weight, the co-ed jokingly replied, "Tell that to my six friends located on my stomach. They don't seem to agree."
