From People:

"It wasn't contentious. It had kind of just run its course … They just sort of looked at each other and said, 'We like each other and we make each other laugh, but this isn't for the long-term.' "

The two had constantly gushed about each other and exclaimed that they were in love. Kennedy was amazed by the multi-talented Hewitt, while Hewitt admired how Kennedy was more than merely a funnyman.
