The actress explained that she had married Hollywood agent Jim Toth just two weeks before Prince William and Kate Middleton tied the knot.
She told the BBC: "I just got married. About two weeks before Kate Middleton!"
Asked if it was a happy day, she replied: "It was, but I didn't have 16 million people watching! I only had, like, 100."
The 35-year-old has been travelling the world with her Water for Elephants co-star Robert Pattinson promoting their new movie, and recalled that they were in Paris on April 29 for the royal wedding.
She also confessed that she went to a great deal of effort to celebrate the future monarch's wedding.
She added: "I really did. I was actually in Paris when the royal wedding happened. It was fun to watch and everyone was excited in Paris, too."
