According to reports, Justin asked Jennifer to work with him on a new screenplay for a comedy film. After Jennifer had tried pitching a few ideas, it seemed as though her fiancé of two years wasn't very impressed with her efforts, leading to a rather big fight between the two and scrapping their wedding plans.

"Are you kidding me? You're the one who pushed me to do this. I wasn't a writer," Jennifer allegedly said, according to the National Enquirer.

A rep for the couple has denied the claims, calling it "complete nonsense." Meanwhile, there are also reports that the two have supposedly set a wedding date for their upcoming nuptials. Jennifer and Justin are to tie the knot two years after they got engaged on Justin's 43nd birthday, on August 10.

The wedding is supposed to be an intimate one, with only the couple's closest friends and family invited.
