Nikki's younger brother Matthew is also an actor, whose credits include two episodes of his sister's series Unhappily Ever After. He credits both Nikki and "Tiffany" with making him the most popular kid in school around that time.
On March 12, 2007, it was announced that Cox had been cast for a role in the CBS pilot "Fugly", from "My Name Is Earl" creator Greg Garcia and focuses on three siblings - identical twin girls and a brother - who pool their resources to get one plastic surgery for one of the girls (Cox).
