Miranda Cosgrove Talks NFL, Fashion and College Life at USC

— -- Miranda Cosgrove is just your normal 21-year-old college student -- except for the fact that she's been starring in movies and TV for more than a decade on shows like "iCarly" and classic hits like "School of Rock."

And while Cosgrove is hard at work, just trying to learn as much as she can at the University of Southern California, some of her classmates also happen to be fans.

Cosgrove just got back to school and said being an actress has its ups and down.

"The weirdest part is after a day at school, I'll go on Instagram or the Internet and there will be pictures of me from school that random people took and I didn't know they took," she told ABC News. "So, that can be kind of weird sometimes."

The good part is it helps her meet new people.

"People come up to me and introduce themselves and it kind of opens the door, so that part of it's nice," she added. "I feel like I'm not the kind of person that would just go up to somebody and introduce myself, so it's helped me in a lot of ways."

Right before school, Cosgrove got her own place, now she kind of regrets it a little, because she would love to live on campus and have the classic college experience.

"I might even try it for a semester at some point, because I do want that experience," she said, adding she decided on majoring in film and "I really want to do screenwriting classes."

In fact, she looks up to the likes of Tina Fey and Kristen Wiig, and admires their ability to both act and write.

"College really does help you grow up and figure out who you are. So, it's just helped me grow as a person, like even just getting to classes on time and figuring out where classes are," she added, laughing.

Cosgrove spoke to ABC as part of her partnership with the NFL as the Tweens/Juniors Apparel brand ambassador. She's a San Francisco 49ers fan and the love of the team comes from her father Tom.

"I'm personally a fan of Colin Kaepernick ... Football also kind of brings everyone together and my dad loves football and loves sports," she said. "For as long as I can remember I've watched football games with my family."

Cosgrove has always been a fan of fashion and sports so this collaboration is perfect, she said.

"Even now that I'm back at school, I like to dress comfortable and I think the shirts [jerseys] are comfortable and cute," she said.
