"Pretty Little Liars" creator Marlene King is developing "Famous in Love" with Rebecca Serle, who wrote the novel the project is based on, MTV reported. According to Thorne, the upcoming series is about "a girl who gets plucked from obscurity from UCLA to star in a new sort of, like, 'Twilight' saga, and it's about her balancing fame and all of that with falling in love with two boys," the news outlet quoted.

"This mirrors a lot of my life," Thorne explained to MTV. "If you ever wondered what it's like to be Kristen Stewart or Natalie Portman or anything like that, we're taking you inside of that. And since we're all actors, we really understand the way it should be."

Aside from being a University of Southern California student, Schwarzenegger also acted in his first movie debut in 2006's "The Benchwarmers," E! News noted. He also has roles in 2012's "Stuck in Love," 2013's "Grown Ups 2," and 2015's "Dear Eleanor."
