Using a Dynavox voice-enhancing machine, Selena chatted with George Lopez about her dear friend Justin Bieber.

"I love him. He's like my little brother," Selena said. "I like to say his name on stage because if I'm performing badly, I say his name and the audience will cheer."

But she doesn't have any sympathy for him when it comes to his height.

"I told him 'No, I'm not going to take off my heels," when Justin asked her to. "You're short, embrace it.' He's getting taller, though."

And as Bieber gets taller, Selena gets older.

The now 18-year-old says she's already found gray hairs!

"Yes! Can you believe I have three?" Selena said. "I freaked out. I ran to my mom and asked her what I should do. I asked if I should pluck them and she said I shouldn't. It's bad luck."
