Remember the movie Can't Hardly Wait? Remember Melissa Joan Hart's uncredited cameo? Well filming that one party scene with Jennifer Love Hewitt made for a pretty amazing behind-the-scenes story where Jennifer Love Hewitt pretty much thought Hart got her high.

Hart stars in Melissa & Joey which returns to ABC Family on Wednesday at 8/7c.
