Being considered one of the most powerful women in the world can be a huge honor, but to be named as someone incredibly influential by the age of 21 seems almost impossible.

However, Seventeen Magazine has revealed their list of the 17 most powerful women in Hollywood who are no older than 21, for their March 2014 "Power" issue.

The list includes several young female singers, actresses, models and even an Olympic gold medalist. Each one was awarded a specific title which qualified her for the list as well.

Tanking in the number one spot was former Disney darling Selena Gomez, whom the magazine labeled as "The Mogul." The 21-year-old singer and actress who is known for her high-profile on/off romance with Justin Bieber has also kept busy with her career. She has also designed clothing lines for Kmart and Adidas, heads a movie production company, has invested in a start-up company, and is the youngest-ever goodwill ambassador for UNICEF. 

She has also garnered a whopping 77-million followers on her three social media accounts (Facebook, Twitter and Instagram), something that she can still hardly believe.

About ranking as number one on the list, Gomez said that this was the year she finally began to feel like a powerful and influential force.

"I had always been the underdog secretly. I was on Disney when it was Miley [Cyrus], the Jonas Brothers, and Demi [Lovato]. I questioned the way I looked, acted sang, and wrote," she said. "Then I turned 20, went through a really bad breakup, and realized I needed to have 'Come & Get It' be amazing. I wanted it all to be me. I'm glad it's taken me this long to get where I am because now I am ready for it."
