"There was just a backlash against me and Jennifer and too much publicity. And then `Gigli' bombed. And we didn't get married," he told reporters recently, according to AP Radio.
He'd worried "what if something bad happens? What if everybody hates my movie? What if I have some public embarrassments in my personal life? Then it all happens in a month, you know, and it turns out like, `All right, well, it's not the end of the world."'
The media frenzy and "Bennifer" label taught him that his fame and career don't affect who he is, the 31-year-old actor said.
"Every movie doesn't have to work. I'm still fundamentally going to be who I am," he said. "It's healthy to want to do well at your job and all that stuff, but you know, it's not this incredibly important thing."
