Has Miley's Heart Been Broken Too Many Times?

Seems like Miley's not so smiley these days.
In fact, she recently told sources that's she's no longer the trusting girl she used to be. "I'm always thinking, 'are you going to tell my secrets?' It's tough," Miley Cyrus said. "When I was younger, I would trust everyone... I find it very hard to trust people now. I definitely protect myself a little more. When people do sweet things for me, I start to think things like, "Ok, what do you want? Are you doing this because you love me or because you need something?' I'm a little hard. But that's just the way my life is."
Aww, Miley! Cheer up. Maybe your budding relationship with Douglas Booth will help you trust people again?
