Maria Shriver ‘Horrified’ Son Patrick Schwarzenegger Dating Miley Cyrus — Not Camelot Material?

Patrick Schwarzenegger may be thrilled to be dating longtime celebrity crush Miley Cyrus. But RadarOnline.com has learned that not everyone is a fan of the new relationship. According to a source close to the family, his mom, Maria Shriver, is “violently” against the pairing!

Cyrus and Schwarzenegger took their new love public with displays of affection at Thursday night’s USC Trojan’s football game in Los Angeles, openly kissing at fan-filled stadium.

“They have been hiding it,” the source says, but the public kissing “was so orchestrated and so planned to be like ‘OK, here you go.’”

Schwarzenegger has made no secret of his crush on Cyrus in recent months. Subsequently, the source says, she reached out to him soon after his 21st birthday in September.

Now, mom Shriver “is horrified,” the source says, and his sisters are also opposed.

“He’ll be very good for her,” the source explained. “But instead of him being a good influence on her, she might be a bad influence on him.”
