"We're still trying to save it," Swank told syndicated TV entertainment show "Access Hollywood" at the Golden Globe Awards, which were presented Monday in Beverly Hills, Calif. "It's not over, we're not divorced. We've been together for over 13 years, and there's a lot of love there."
Swank, who wore her wedding ring to the awards ceremony, added: "We're still married."
Swank, 31, and Lowe, 38, announced their split Jan. 9. They were married in 1997 and have no children.
The actress, who won Oscars for "Boys Don't Cry" and "Million Dollar Baby," next stars in the Brian De Palma-directed crime drama, "The Black Dahlia."
Lowe won an Emmy Award in 1993 for his performance on the U.S. TV series "Life Goes On."
