Selena Gomez has revealed one surprising difference between her and best friend Taylor Swift.

In an interview with Teen Vogue for their December/January issue, Gomez says, "The difference between Taylor and me is she was 16 with the confidence of a 25-year-old. Actually, I should say 80-year-old, because she's such an old soul."

Hypothesizing why she lacks in confidence compared to Swift, Gomez says, "I was not that way. I was very sheltered until about 18 or 19. I still live at home, and I'm 21! She does inspire me like crazy, but I wouldn't change my path, because it allowed me to figure out all that stuff and do it on my own.

"I'm 21, so now I've entered the decade of confusion about who I am and what I want to do with my life, and that's what this entire decade's going to be."

As for her love life, Gomez seemed to reference her break up with Justin Bieber when she told the magazine, "You fall in love and it completely consumes you. So a part of you is broken when that's gone. And part of you wants to have that rebellious feeling where you're just like, forget it—I can do anything I want. I've tried it, and I've never been that girl. I'm always going to be the girl you want to take home to your parents, not for the night."
