Jack Nicholson and Diane Keaton attend a photo call at the Berlin Film Festival for their movie 'Somethings Got To Give' 06.02.04

The ANNIE HALL actress revealed her feelings for her SOMETHING'S GOTTA GIVE co-star on hit chat show THE OPRAH WINFREY SHOW.

She lamented, "He's the man I love. But he doesn't feel that way about me."

Nicholson later responded to her confession diplomatically, telling the New York Daily News, "Just like me, everybody loves Diane Keaton."

He then jokingly advised her to "invest more in heavy sexual acts. Not too distorted, but at least interesting in nature."
