If anyone is starved for a red-carpet fix during the quiet summer months, relief comes in the form of the Teen Choice Awards. Starlet Victoria Justice will host the fan-voted show, which airs at 8 p.m. Sunday on Fox. The 23-year-old has been a regular at the event since she was first nominated in 2010 for “Choice Smile.”

Among those up for this year’s honors are Selena Gomez, Demi Lovato, Miles Teller, Gal Gadot, Jena Malone, John Boyega, Daisy Ridley, Jennifer Lawrence, Shailene Woodley, Chris Evans and Chris Hemsworth.

Justice knows the teenage demographic well, as she began her acting at age 10 on “The Gilmore Girls” and starred in Nickelodeon series “Zoey 101,” “Victorious,” “The Troop” and “iCarly.” Last year, she played the lead in the MTV cyber thriller series “Eye Candy.” Here, she shares with WWD what to expect on Sunday.

WWD: What part of the show are you most excited about?
Victoria Justice:
I’m mainly excited to goof off with [cohost] John Cena. I feel like he has to lift me at some point; that is necessary. I’ve never hosted anything live like this, so I’m a little nervous.

WWD: What are you going to wear?
For the red carpet I’m wearing a Versace dress, which was the first one I tried on. It’s a little mini and it’s sexy, fun and colorful. It’s always really hot at the Teen Choice awards, so you want to stay cool. For the show I have five costume changes for all the sketches. We’ll see if I end up wearing all of them.

WWD: What red-carpet advice would you give other young women going to an event like this?
Dressing appropriately for the event is always key, and so is knowing your audience. The most important thing I’d encourage people to do is to not get too caught up in what designer they are wearing. Sometimes it’s not about the biggest name you can wear, it’s about what fits you best. Fit is really important. I’ve been lucky to be able to wear designers like Versace, but I’ve also worn H&M on a red carpet.

WWD: What did you wear to your first Teen Choice Awards, back in 2010?
I wore this turquoise BCBG dress and I blended in with the backdrop of the carpet. So, it helps to know the color of the step-and-repeat beforehand.

WWD: Who are you most looking forward to meeting on Sunday?
I’d love to meet Justin Timberlake and get a picture with him.

WWD: I’m surprised you haven’t met him before at one of these things.
Actually I met him when I was like 12 or 13 at the “Shrek” premiere. I asked to take a picture with him and his publicist was like, “No,” but he saw me ask and was like, “No, no, it’s OK, I’ll do it.” It would be cool to get another one so many years later.

WWD: You also performed songs on several of your shows and have toured with other teen singers. Who do you most admire in the musical world?
I’ve always been a big fan of the singer-songwriters. I love Lily Allen, Sara Bareilles, Gwen Stefani. I love how fearless she is on stage. I also love Chris Martin as a performer and songwriter, and Bruno Mars. Amy Winehouse is also really inspiring.

WWD: What projects do you have coming up?
 “The Rocky Horror Picture Show” will air Oct. 20 on Fox. I have a development deal with Fox to create or be a part of a new show, so we’re working on some ideas. I’m also going to start getting back into the recording studio.

WWD: What’s the best part of performing onstage for you?
The energy of the crowd. There’s not anything else like it in the world. It’s such an incredible high seeing fans sing along who know the words to some of your songs. I love how music has the power to uplift and inspire people.

WWD: Whose performance are you most excited to see on Sunday?
Serayah McNeill from “Empire,” Charlie Puth, Flo Rida and a surprise performer I can’t reveal just yet. I’m a really big fan of this person.
