The Bride Wars star – who is divorced from Black Crowes frontman Chris Robinson – has not ruled out marrying again, but wants to avoid the “big production” of a huge wedding.
She said: “Who knows if I will get married again? I wouldn’t rule it out though. But I would elope and then have a party.”
Kate, who has a four-year-old son Ryder with Chris, also revealed she thinks weddings are often like movie premieres because they are so chaotic.
The 29-year-old actress – who has previously been romantically linked to Owen Wilson and Lance Armstrong - added: “It gets so screwed up because you’re dealing with two families, you’re dealing with your parents - some parents try to stay out of it, but they always have to have their word. You’re in an awkward position. It’s like a movie premiere. It’s a big production.”
Kate stars alongside Anne Hathaway in new romantic comedy Bride Wars, which tells the story of two friends forced to compete after discovering they have booked their weddings on the same day, in the same location.
