Jolene K. Blalock (born March 5, 1975) is an American film and television actress and model, best known for playing the Vulcan T'Pol on the UPN science fiction series Star Trek: Enterprise. The star of several feature films, she is a regular guest star in television films and series.
A popular model, Blalock left home at 17 to model in Europe and Asia. She has appeared on the cover of many men's lifestyle magazines and was twice featured in Maxim's "Girls of Maxim" gallery. She posed for a clothed fashion layout in Playboy in April 2002. She was later interviewed by the magazine for its "20Q" section in February 2005.
Blalock spent years dieting as a model and was relieved to move into acting, saying: "I'm jaded by my experiences in the modeling industry. You're never skinny or perfect enough, and it was difficult mentally making the transition to acting."
She made her television debut in sitcom Veronica's Closet, before guest appearances in The Love Boat: The Next Wave, CSI: Crime Scene Investigation, JAG, and starring as Medea in a 2000 adaptation of Jason and the Argonauts. TV movie On the Edge and mini-series Diamond Hunters, in South Africa, paved the way for Star Trek prequel Enterprise.
