Looks like Miley Cyrus is winning over the family. Though the pop star and her pizza-shilling boyfriend, Patrick Schwarzenegger, have been plagued by reports that his family — specifically mother Maria Shriver — doesn't approve of their romance, his older sister had nothing but good things to say. In an interview with Extra, 25-year-old Katherine Schwarzenegger called the couple "adorable," adding that she just wanted the best for her little brother. "You just want your sibling to be happy," the lifestyle site founder told Mario Lopez. "If they’re with someone who makes them happy and in a happy healthy relationship then I’m happy.” Fair enough. With Papa Arnold spending time with the couple and other Kennedys offering their approval, it would appear as though Cyrus is golden. There's just one catch: Mama Shriver's social media crackdown. “She makes us put our phones in the center of the table so no one is on them," Katherine revealed. Miley without access to Instagram? Torture.
