"Stuart always wants the truth, and I always want the truth from him -- and the truth is that he's incredibly talented," Charlize says of her beau's work.

The downside of working with her love?

"It ruined many vacations that were supposed to be romantic," she said playfully. "Fiji all of a sudden became so un-sexy."

In theaters Friday, 'Battle in Seattle' finds Charlize playing a peaceful activist caught up in a full-scale riot alongside the all-star cast of Woody Harrelson, Ray Liotta, Andre Benjamin, Connie Nielsen, Joshua Jackson, Channing Tatum and Michelle Rodriguez. The film is based on a real-life, five-day stretch of pandemonium that ensued when demonstrators protested a meeting of the World Trade Organization in 1999.
