Chatting to reporters on the red carpet at the "Killers" world premiere last night, Katherine explained that she contemplated bringing daughter Naleigh to the event and joked, "I thought about it actually. Would it be bad if we walked her down the carpet. She can walk now, so she would have carried her own weight." She added, "It is hard, I left her home tonight, she was very happy playing though with her babysitter."

Katherine was all smiles as she told ET, "I always feel like a movie star every time I get to walk a red carpet. I don't know, I don't care if it's like TV or just a dog event I am going to, it just always feels fabulous when you walk a red carpet. It is hard to resist."

Maximo TV was also at the premiere to record proceedings, shooting Katherine as she posed for photographers with co-star Ashton Kutcher, director Robert Luketic and her husband Josh Kelley.

The topic of memorable first dates was a question posed for both Katherine and her co-star Ashton Kutcher as the duo made their way down the press line. Remembering how she first met her husband after appearing in the music video for his song "Only You", Katie described how the couple enjoyed dinner at the Beverly Wilshire Hotel after the shoot and that Josh played one of his songs for her on the piano.
