Katie Holmes is threatening legal action against an actress who changed her name to Katee Holmes and said she plans to lose her virginity in a porn movie.
Katee, 18, is due to star in the adult film later this year and has announced one scene will see her have sex for the first time.
Katee's manager said, "She's using the name as a tribute to Katie, who has always portrayed innocence in whatever she has done."
However, a spokesman for Katie Holmes said, "It's a really cheap shot. Obviously Tom would support Katie in anything she decides to do about it."
