Seyer said she can't tell every detail about the commercial, but she did say for the shoot, she had to pour 30 bottles of PowerAde and Gatorade on herself in 40-degree weather.
"It's very racy for the Super Bowl and extremely racy for PowerAde," said Seyer during a phone interview Friday from her parents' home in Oran. Seyer was in town visiting her family for the holidays.
"It was a risky commercial for PowerAde, and I can't say that my dad's really gonna enjoy it, but, hopefully, 95 percent of the male population will enjoy watching it," she laughed.
Since representing Missouri in the 2007 Miss USA Pageant where she placed 10th overall, Seyer has lived in Los Angeles where she works full-time as a model.
Seyer said she doesn't know the time slot the commercial will appear, but it's slated to run sometime during the broadcast of Super Bowl XLIII, which airs at 5 p.m. Feb. 1 on NBC.
Seyer shot the television commercial Dec. 19 in Irwindale, Calif.
"It was pretty cool, and we had a great day (other than the cold weather)," Seyer said about the shoot. "I have never had to be so sexy and so miserable at the same."
Her favorite part of the shoot was the elderly security guard at the park who ended up being cast in the commercial, Seyer said.
"He was sitting there and telling all these ladies, 'Wow, you sure are a beauty,' and things like that. ... He was like a grandpa -- so cute and funny," Seyer said.
Because of his charm, a part was added just for the security guard.
"We became buddies on set. He was so humble and sweet and funny. He reminded me of someone from Missouri, and he was a good guy," Seyer said of the man.
Seyer said she goes on casting calls daily in L.A.
"The way it works is you go to a casting studio, and they tell you what to wear, and for PowerAde, I had to wear a sports bra and spandex -- but you don't know what you're going to have to do," Seyer said.
For this audition, the agency was looking for twins so two girls were being videotaped at one time -- one was drinking Gatorade and the other PowerAde, Seyer recalled.
"You never know if they're looking for a blonde, a brunette or a muscle type, and you just do what they ask," Seyer said.
Seyer said she was asked her name and a snapshot was taken of her. She then acted out roles on command. For example, she was asked to act like spokesmodel -- all while standing on an "X" -- then be really happy and then seductive. Then she had to pretend like they were drinking the PowerAde or Gatorade.
Once an audition is finished, Seyer said she waits for a callback.
"That means if they like what you did the first time, they want you to come back and do it a second time," Seyer said.
In the second round, Seyer was still competing against about 40 girls. She went back and did the same thing as before. She got called back for a third audition. This time there were seven girls -- three brunettes and four blondes, and the girls auditioned in front of PowerAde clients.
The fitting for the casting was on Monday; final casting was on Thursday, and by that Monday morning, Seyer received a phone call that she'd been booked for the commercial. It was also then she learned the ad was for the Super Bowl.
"I was in a hardware store buying paint when I got the call," Seyer recalled. "I was so excited."
While she often gets callbacks, it's not everyday, Seyer gets booked for a casting, she said.
And that's something Seyer is fine with, and she doesn't get nervous during castings anymore either, she said.
"I feel like everything happens for a reason," Seyer, said
Internet users likely recognize Seyer from the Earn a Degree online advertisement. She also is an infomercial for the make-up brand Bare Escentuals.
"I'm modeling full-time and dabble in the acting industry, and commercials are getting me there," Seyer said.
Seyer, who has turned down offers to work in Japan and Europe, has also modeled for catalogs, clothing companies and brands like J Brand jeans, Joe's Jeans and Ed Hardy. She has done a lot of runway modeling, and on Wednesday, she will meet with agents from San Francisco, Germany, and Miami, Fla.
"I'm very happy in L.A., and I didn't realize I could be happy in a city atmosphere," said Seyer said, who lives in an apartment with her two dogs.
Seyer has also been to "The Hills" star and fashion designer Lauren Conrad's home for model work.
"She is really cool and down to earth," Seyer said about Conrad.
Seyer compared the commonality of seeing celebrities in L.A. to that of visiting characters at Disneyland, only to see them take off their masks.
"It kind of takes the magic away," she said.
Just being able to work full-time in her profession, especially in the midst of a recession, makes Seyer feel extremely blessed, she said.
"As far as a my career industry, it's not the greatest time for it, but work keeps coming for me," Seyer said. "I'm happy where I'm at, and for now, I'm going to stay in L.A."
