Arnold Schwarzenegger and Maria Shriver's oldest son, Patrick, is showing some skin! A billboard of the 17-year-old's shirtless ad campaign for Hudson Jeans is prominently showcased above a bar called Happy Endings on Sunset Boulevard in Los Angeles.

But don't think modeling is Patrick's only ambition. Earlier this week, he tweeted about his college tour. "Just visited Harvard University," he said. "Great college, but I'm not adding it to the list."

So where does he want to go? "Stanford, USC, Penn [and] Georgetown are my tops for now," he said. (His mom, 55, is an alumna of Georgetown University, where she received a Bachelor of Arts degree in American Studies in 1977.)

Since the news of his parents' split went public in May, Patrick has been adamant that family remains his top priority. "Small speed bump in life," he tweeted. "Luckily we all own hummers. We will cruise right over it. All will be okay. Peace."
