The `Killers` actress - who raises adopted 17-month-old daughter with spouse Josh Kelley - thinks she would make a terrible secret agent because she always gives things away, though she takes pleasure in concealing herself in strange places.

She said: "I`d be a terrible secret agent. I can`t keep a secret and I`m not sneaky. Though I have to say I am very good at hiding. I can hide, and my husband`s just terrible at finding me. I do like to jump out from behind doors and scare him."

As well as enjoying frightening Josh, Katherine admits she isn`t afraid to tell the singer what she thinks of him - even if it makes him upset.

She told Parade.com: "There are some things that if you say them out loud it will hurt the other person`s feelings. I tend to say them anyway because I think it`s better to be honest. I gave a really hard time recently because he got this new haircut for a photo on the country album he`s releasing.

"I really didn`t like it, even though everybody else loved it. I was like, `You don`t look like you. You`re really sexy, you`re a manly man and this is kind of a metrosexual look.` Finally, he just stopped listening to me."
