"I approve of whatever makes my brother happy," Katherine said about the relationship at last night's premiere of Dior and I. So wait, does that mean he's happy right now...happy with Miley?
"He's a 21-year-old college kid, how could he not be?" she responded. Hmm, why so fake? That kind of sounds like a cheap way of sticking up for him and his lame, player ways at Spring Break a few weeks ago. She KNOWS what we all wanted to hear!
Katherine is Maria Shriver and Arnold Schwarzenegger's oldest child, and last night was a monumental moment for her. She had never work Dior until she slipped into one of their dresses last night.
"It's my first time!" she said. "I lost my Dior virginity."
She wasn't the only one to open up to E! at the event. Taylor Swift's BFF Jaime King talked to them about her new boo Calvin Harris, too.
Do you think Katherine really likes her bro dating Miley? Think those two will last?
