The three co-starred in 2010's 'Love and Other Drugs.'

Who knew an old pic of Jake Gyllenhaal could cause this much commotion? 

Josh Gad and Anne Hathaway traded a few jabs over Instagram on Thursday, after Gad posted a throwback shot of himself and Gyllenhaal on the set of Love and Other Drugs. 

"#tbt Wow. Here’s an oldie but a goodie. #jakegyllenhaal and I behind the scenes during #loveandotherdrugs," Gad captioned the pic, not long before Hathaway got in on the action. 

"I’m not sure if you’ll remember me but I was in Love and Other Drugs with you,” wrote the 35-year-old actress, who also starred in the movie. “My name is Annie? Anyway, I hope you are well! (Please like my comment, it would mean so much to me!)”

"@annehathaway please reach out to my agent,” Gad responded to Hathaway's comment. “That’s where I have my fan mail sent. Thank you!!"

Hathaway starred in the 2010 film as a Parkinson's patient who falls in love with a pharmaceutical salesman (Gyllenhaal). Gad played Gyllenhaal's brother. 

It was another co-star, however, whom Hathaway couldn't stop talking about during a recent appearance on The Ellen DeGeneres Show. Find out what advice Hathaway's Ocean's 8 pal, Rihanna, gave her on her post-baby body in the video below.
