When she was younger, casting directors would tell her she wasn't "pretty enough," she said, but after ABC sportscaster Brent Musberger spotted her in the stands of the University of Miami-Florida State University football game in 2005, things changed.
That turned out to be her big break, and she ran with it, posing for Playboy and Maxim. She eventually got the job with the Jets. The combination sports and entertainment position fulfilled her love for sports and for entertaining others, she said.
"There's nothing that feels quite as awesome as walking through the tunnel on a game day, in the Meadowlands," she said. "It's just this surge of electricity. I can't explain it. It's amazing."
She wasn't the only newcomer to the Jets that year. After 16 years with the Green Bay Packers, Favre joined the Jets. Sterger said it didn't take long for her to be approached.
"I was approached one day at the beginning of the pre-season games, by a man wearing a Jets badge, employee badge, who asked me, 'How would you feel if Brett Favre asked for your phone number? What would you say?' And I just looked at him, my usual smartass self. And I said, 'I'd say I like my job an awful lot. And I've been told I look remarkably like his wife,'" she said.
She said she walked away without giving the man her number and thought "that was the end of it."
But she said she started getting text messages, then voicemails. She said she didn't know who was reaching out to her.
"Whenever I would reply, it was more to try to figure out who I was interacting with," she said. "It was the same number, always. The texts, the pictures. The voicemails. There was no actual, 'Hey, Jenn. It's Brett.'"
But she said she was able to figure it out.
"It was all context clues ... They would always give me the pieces of the puzzle. Forty years old. Gray hair. New to the team. That only fits a few guys on the team ... No, only one guy on the team," she said. "I always noticed that he was looking at me in the tunnel. I just had that gut feeling. I really did."
Sterger said she wasn't flattered by the attention from Favre.
"He's married. And more than anything I feel like it was intimidating," she said.
She kept quiet about it because she didn't want to make waves at her job, she said. She said she consulted several people, described what was happening and asked for advice.
"And every single one of them gave me the exact same answer. They said, 'Jenn, do you like your job? Well, if you like your job, and you want to keep it, I'd suggest you just be quiet. Do your job,'" she recalled.
She kept doing her job, and kept putting off Favre, she said.
"It's staving him off. It's 'I'm busy. I'll talk to you later. I'm busy. I'm busy.' He was like that guy at the bar that just could not get the hint. I'm busy," she said.
Then, she says she received nude pictures of Favre. It was at that point that she says she realized "just how serious it is and that this isn't going to go away."
At the end of the 2008 season, the exchanges stopped, but resumed briefly in 2009, she said.
"It's kind of like that last ditch, Hail Mary effort. But that was it. It was gone. I didn't respond," she said.
