Danielle Davies launched a website called "My Life With Bradley Cooper" and also has an accompanying Instagram account.
"Because, friends, this is America. So why not?" the 39-year-old wrote on her site. "The fact is, while most of us don't actually live our lives with movie stars, many of us wish we did. If I want a life with Bradley Cooper, well, then...I'll just make one up."
Davies is married to "possibly the most patient husband in the world" and also has a son and daughter.
She reflected about the different directions that her and Cooper's lives have taken since college.
"Since then, he's become startlingly famous and I ... not so much," Davies told TODAY. "(The pictures are) a way for me to poke fun at how I ended up, where I am and how/why my one-time stage equal has gone on to become an Academy Award nominee."
Davies plans to turn her project into a book.
"Sometimes, people just stare and then totally avert their eyes," Davies said. "That's definitely the weirdest ... maybe they don't get that it's a joke? I don't know, but they are clearly uncomfortable!"
