Chris O'Donnell and Wife Caroline Fentress Expecting Fifth Child

Chris O'Donnell and his wife, Caroline Fentress, are expecting their fifth child.

When asked about his four children during an appearance on NBC's "Today" show, the 37-year-old actor said there was "another on the way."

"We're just starting to figure out how it works," he said Wednesday. "I think I know why this is happening, but we're gonna figure it out. Very excited, though. We're really excited about it."

The couple, who were married in 1997, have three boys and a girl. Fentress gave birth to their fourth child last year.

O'Donnell's screen credits include "Batman Forever" and "Scent of a Woman." He stars in the miniseries "The Company," which premieres Sunday on TNT.
