James Cameron isn't nervous about being up against his ex-wife Kathryn Bigelow in the Best Director category at the Academy Awards Sunday in Hollywood.

Look back at the worst Oscar dresses of all time!

On E!'s pre-Oscar special, the Avatar director, 55, said he and his ex-wife, who directed The Hurt Locker, "don't feel any sense of competition between ourselves."

Cameron added he and his current wife, Suzy Amis, were "big supporters" of Bigelow's work.

"We both couldn't be more proud of what Kathryn has accomplished," he said. "We're very supportive."

To prove there's no ill will, he said they often consult each other on different projects.

"She sees my films when I'm writing them and cutting them and vice versa," he said. "She saw Avatar five times at different stages and gave notes. So we're actually helping each other!"

He added that he even encouraged her to direct The Hurt Locker. He said he told her it was a "no-brainer" that she should "make this movie now."
