Well, the 22-year-old country star did join 18-year-old Patrick and his family at the Kennedy compound in Cape Cod.
Arnold Schwarzenegger's son, who's matriculating at the University of Southern California in the fall, was photographed giving Taylor a friendly hug, and the duo was also spotted together on the beach.
"Had such an amazing day," Patrick tweeted. "Best 4th of July I could ask for. Hope everyone had a great day!"
Taylor has yet to tweet about her holiday with Patrick & Co. If they do start dating, she better watch out: Schwarzenegger, (unlike, say, John Mayer) sure is a tough one to rhyme.
