In 1994, she was discovered by Swedish porn director Nic Cramer and appeared in two of his videos, Euro-max 2 and Euro-max 3. This introduced her to the American porn industry. She soon left France for Los Angeles and quickly established herself in the porn industry there. She has since appeared in over 200 porn movies (as of 2007). Lord has directed and produced several of the videos she has starred in, through her company, Rebecca Lord Productions, as well as actively maintaining an internet paysite. She became much less active in porn movies after 2003, though in several posts on her website (in July 2004, November 2005, and March 2007), Lord denied rumors that she had retired.

She has used condoms in almost all of her sex scenes with men, and has noted that the pressure on actresses to work without condoms has caused her some difficulty in the industry. Throughout her entire porn career, she has been married to the same man, who she has been together with since the age of 17.

During her time in the USA, Lord has lived in Los Angeles, Las Vegas, San Francisco, and New York City. As of 2007, she has been living back in France for several years, after her the expiration of her visa (which expired during the filming of I am a Sex Addict). She has stated that Las Vegas and New York are two favorite cities and that she plans to move back to one or the other city in the future.
