It looks as though Kylie Jenner has answered everyone's questions as to why she is looking much curvier these days. The 17-year-old has admitted that she's gained 15 pounds in the past year by sharing a throwback photo of her much "skinnier" frame on her Instagram account this past weekend.

Speaking to Fault magazine this week, Kim Kardashian's little sister said that being a good role model while in the public eye is not her "focus" these days.

She said, "I never feel pressure to be a good role model. I always try to do my best to inspire people to be good and do the right thing, but I just can't live my life always trying to be a good role model. I try to be the best I can be, but it's hard sometimes. We're all human. I just like to live each day and just be me and be real."

She added, "People are going to judge you no matter what you do. So now I feel like I haven't been open as much as I used to be. I haven't really been letting my fans get to know me a lot; I closed down a little. I love to connect with people, but it became just a bigger door for people to judge me."
