Actress Diane Kruger has confessed she used to be slightly manipulative in her past relationships.

The 37-year-old says playing crafty bride-to-be Isabelle in French film `A Perfect Plan`, out in Britain this June, has made her realise she's been guilty of using her womanly charms to her advantage in the past when it comes to men.

"Maybe (I'm]) not like Isabelle, but I've certainly been guilty in the past of being slightly manipulative when it comes to boyfriends. I think, as women, we know instinctively how to push men's buttons,` contactmusic.com quoted her as saying.

"We know which fights to pick and which to leave. And we know that if we pick a certain type of dress, we'll get a certain type of reaction,` she added.
