Rebecca moved to New York at age 15 to pursue a career in modeling and acting, and finished her high school education after having initially spent a summer there modeling.

She completed the rest of her high school years at New York's Professional Children's School, and then moved on to study at the Lee Strasberg Institute.

Midway through her second term at the school, Rebecca became a cast regular on the daytime soap opera Loving (1983) in which she played a student obsessed with her professor.

Her modeling career started in advertisements, in which Rebecca began modeling underwear in Sears and JCPenney catalogs, but it was her turn as the Noxzema girl that merited her national recognition.

For the next few years after that, Rebecca worked steadily in television. Her credits include Beverly Hills, 90210 (1990), the alien-esque series Earth 2 (1994 -- this show placed Rebecca in the hearts of many fans in Germany where the show was a huge hit), and the NBC miniseries Invasion (1997).

 By 1997, Rebecca began starring in big-screen movies such as Nothing To Lose starring Tim Robbins and the emotionally unstable Martin Lawrence, and Scream 2 alongside Neve Campbell, Courtney Cox-Arquette and David Arquette, in which she played a sorority sister named Lois. Her part in the film was short-lived, but memorable enough to get her cast in more movies.

In 1998, Rebecca starred in Urban Legend and in 1999, she starred alongside Rose McGowan and Pam Grier in Jawbreaker, and then nabbed a leading role in the disappointing movie Puppet, directed by Felix R. Limardo.

In 1999, Rebecca returned to television and starred in the short-lived drama entitled Wasteland, but the show was canceled soon after it aired.

Rebecca kept up her attempt to make it big in film by then starring in the Quentin Tarantino vehicle From Dusk Till Dawn 3: The Hangman's Daughter (2000), and although it received some praise, it didn't do very well at the box office.

In 2001, Rebecca starred in three movies: Hairshirt, co-produced by and starring Neve Campbell, Doppelganger and Harvard Man, with Sarah Michelle Gellar and Eric Stolz.
