The 17-year-old blonde talked exclusively to StyleList about the show, being a curvy girl in Hollywood, and growing up with The Hoff as her dad.
StyleList: Since you've never been to a weight-loss camp personally, how did you research this role?
Hayley Hasselhoff: "Huge" has an amazing team of writers that helped me connect with my character and also gave me the opportunity to find her within myself. I got to create her journey from my own imagination using what they've shared.
SL: You play the most popular girl at camp. Were you popular in high school?
HH: I guess you could say that. [laughs] I was the girl who tried to make friends with everyone. It didn't matter who was cool or not, what grade they were in; it was more about the person they were.
SL: Growing up in Hollywood, was it a difficult being a curvier girl?
HH: I think growing up anywhere, teenage girls tend to struggle [with] accepting their bodies. It took me a while to recognize that I need to love what God gave me and be comfortable in my own skin, no matter what size I am. I can now say I love myself for who I am and that has a lot to do with recognizing it's not what's on the outside but what comes from within.
SL: You've done some plus-size modeling in the past. What do you think of girls like Crystal Renn getting more exposure on the runway and in magazines?
HH: I think it's amazing that society is starting to realize that people come in all shapes and sizes, so why should we only advertise one size? Half of America is plus-size, and it's time to publicize that notion in a positive way. Plus-size models have been around for years, but it's finally being exposed, and real women and their bodies are being flaunted.
SL: What memories do you have from the set of "Baywatch"?
HH: I grew up on the set, so my dad's trailer was like my wonderland. There are too many memories to break down, but I will say that those memories were definitely a highlight of my childhood.
SL: Was is awkward knowing people thought of your father as a sex symbol?
HH: People are going to label every celebrity whatever way they want. To be labeled anything in the entertainment business is a privilege.
SL: You have great style. Do you ever give your father fashion advice?
HH: My dad has great fashion sense, but I love going shopping with him to dress him and show him some new outfits. I get so excited to take him shopping. I always send photos to my sister as we're shopping to show my outfit creations for him.
SL: What fashion tips do you have for girls with curves?
HH: Always embrace your curves and flaunt them in the right ways. The best fashion advice I've had passed down from my mother is to always dress like a classy young lady and never show too much skin. If your legs are visible, make sure your bust is covered!
You can catch Hasselhoff on "Huge" at 9pm ET on ABC Family.
