Rebecca Romijn (pronounced ro-maine) is an American film and television actress and former fashion model. She is the daughter of Elizabeth (née Kuizenga), a public school English teacher and textbook author, and Jaap Romijn, a custom furniture maker. Her father, a native of Barneveld, The Netherlands, is Dutch, and her mother is a second-generation Dutch American who met Romijn's father while studying in Europe. While studying music (voice) at the University of California, Santa Cruz, Romijn became involved with fashion modelling and eventually moved to Paris for more than two years.

Among other jobs, Romijn modelled for the swimsuit issue of Sports Illustrated and for Victoria's Secret. She also was the host of MTV's House of Style from 1998 to 2000.

In 2000's X-Men, Romijn had her first major movie role as "Mystique"; she returned to the role in 2003's sequel X2: X-Men United, and again for X-Men: The Last Stand (2006). In these movies her costume consisted of blue makeup and some strategically placed prosthetics on her otherwise nude body. She had her first leading role in Brian De Palma's Femme Fatale (2002). She also has starred in movies such as Rollerball, The Punisher and Godsend. She played the leading role in Pepper Dennis, a short-lived TV series on The WB. This series showcased Romijn's talents for comedy, singing, modelling, drama, and adventure.

You know, in my early twenties I wondered if I was interested in women and so I kind of, well ... did my homework. [Grins] And it turns out I'm pretty straight.
