NEW YORK CITY, NEW YORK: Jennifer Lawrence revealed how she coaxed her co-star Andrew Barth Feldman to shelve his studies at Harvard University to star in the comedy movie 'No Hard Feelings' while speaking to ET Online in New York City on Tuesday, June 20.

"I mean, when Andrew left his audition, the door closed and we all looked at each other and we were like, 'That's our -- that's Percy,' and then they were like there's one complication, he's supposed to go to Harvard, and we were like, 'Is that a joke?'"

'You're not gonna be able to finish your semester'

"He was fully the character, so I called him and said, 'Andrew, I have really bad news you're not gonna be able to finish your semester at Harvard,'" she continued. "He's gonna have to defer, or whatever college school words are."

What did Andrew say about the incident?

When the 21-year-old was asked about how he felt about putting a hold on his education, he told the outlet that he could not decline the unparalleled opportunity to act in the film. "Of course," he said when asked if he still stands by his decision. "Harvard is still there. I can go back, but this movie was once in a lifetime."

Andrew learned a lot of things from Jennifer

"This is an industry I care so much about; this is a movie I care so much about, and from her, I learned how to be kind and do all of this. How to do all of this and keep a head on my shoulders," Feldman shared. "Let the, you know, the Jennifer Lawrence of it all -- she lets it fade into the background so much. She's a person first, she's a mother first, she's a friend first and that was a huge, huge thing to learn." He added, "I think getting a stylist and a publicist and all these things I have no idea how to do. We just did a whole press tour together. I learned everything from her. She's amazing."

Although the movie has a few intimate moments, Feldman said it was important for them to have faith in each other, which was instant for the co-stars right from the get-go. "It was truly right away. I think there was just something very kindred between the two of us, and day one we were just like oversharing, telling each other our deepest darkest secrets," Feldman said. "There was nothing we were not game for because we trusted, and we trust each other so much."
