McKenzie Westmore (born 26 April 1977; age 41) is the daughter of Star Trek makeup artist Michael Westmore. She is the sister of Michael Westmore, Jr., niece of Monty and June Westmore, and grand-niece of Star Trek: The Original Series hair stylist Pat Westmore.
She has also performed occasional extra work in the Star Trek franchise. As a young child, she portrayed the character of Rose in TNG: "When The Bough Breaks". Later as an adult she appeared as the character of Ensign Jenkins in VOY: "Warhead".
In 2009, she was interviewed for the special feature "Westmore's Legacy" on the Star Trek: The Next Generation Motion Picture Collection (DVD) edition of Star Trek: Insurrection. She mentioned that she worked as a camera test model and a make-up test model for the Ba'ku and that she also portrayed a Ba'ku with one line of dialogue which ended up on the floor of the cutting room. Michael Westmore proudly enthused, "I liked watching McKenzie work on the show." (Star Trek Monthly issue 110, p. 37)
Westmore's acting debut was at the age of two, in the 1980 film Raging Bull, where she portrayed the daughter of Robert De Niro's character, Jake LaMotta. Her appearance in the film was at De Niro's request, after the two built a relationship on the film's set, as her father served as film's make-up creator. (Makeup Man: From Rocky to Star Trek, p. 127)
