Leslie Mann sometimes thinks Judd Apatow is plotting to kill her. The 40-year-old actress joked her husband may want to hire someone to get rid of her, but she isn't sure why.

She said: "Do you ever have that feeling that your husband might be plotting to kill you? Sometimes when I'm alone at home I think that Judd might have set up a hit-man to murder me. But he says he never thinks like that."

The couple worked together on new film This is 40 - written, directed and produced by Judd - which was inspired by their own married life.

Leslie explained her husband sometimes hides in the bathroom, which she found out when she noticed him tweeting while he was in there. Unlike in the film, she didn't want to walk in and confront him there though.
