And so it appears Mama Bear Maria Shriver does not want her son to be the victim subject of Taylor Swift's next hit song!

A week after TMZ first reported Taylor, 22, spent the 4th of July flirting up a storm with Patrick Schwarzenegger, 18, a new report is now stating Maria, 55, does NOT want her son dating Taylor.

According to the latest issue of the National Enquirer, Maria fears Taylor will chew Patrick up, spit him out and then write a song about him as she's done with previous famous boyfriends. Your hunch is right Maria!

"Maria got word to Taylor and warned her not to get any ideas about dating Patrick," reveals an insider. "She basically told Taylor to 'back off.'"

The insider adds: "Maria is worried that Taylor will lead Patrick on and then leave his heart shattered in a million pieces, like she's done with other guys."

The good news is that Maria does think, Taylor who is a longtime Kennedy family friend, is a sweet girl, but just not sweet enough for her baby! "She's 100 percent opposed to Patrick dating her," says the insider. "He's entering the University of Southern California in the fall and she doesn't want anything distracting him."
