That is what's currently listed on her IMDb page (https://www.imdb.com/name/nm0185178/) for instance. But then, if you go on her Wikipedia article (https://en.wikipedia.org/wiki/Nikki_Cox), it currently says that she was born in either 1974 or 1975.

For what it's worth, this article (https://www.newspapers.com/article/the-kalamazoo-gazette/164671242/) from December 1995 says that she's 19 years old. But then again, this other article (https://www.newspapers.com/article/fort-worth-star-telegram/164671547/) which is also from December 1995, says that her date of birth is June 2, 1978.
