It's sometimes hard to believe that the country cutie is only 23.
Is Taylor Swift a 22-year-old cougar?
Swift took a romantic stroll on the beach with Arnold Schwarzenegger and Maria Shriver’s son for July 4.
The singer, 22, spent the holiday hanging with Patrick Schwarzenegger, 18, TMZ reports.
The pair were seen in Massachusetts together “laughing,” and “taking a private stroll along the beach.”
The site also reports the pair was seen with “several members of the Kennedy family.” Patrick’s grandmother was the late Eunice Kennedy Shriver.
Swift has previously been friendly with the Kennedy clan. FOX411 was there when she hung with numerous members of the famous family at a premiere of Rory Kennedy’s HBO doc, “Ethel” -- about Kennedy’s mom Ethel Skakel Kennedy -- at the Sundance Film Festival this year.
At the time Swift said, “The only time in my life I have ever been starstruck was meeting Caroline and Ethel Kennedy,” she said.
Swift’s been linked to beaus including John Mayer, Joe Jonas and Jake Gyllenhaal.
She was also rumored to have been seeing Jets quarterback Tim Tebow.
Patrick is a male model and has his own philanthropic clothing line.
