Campbell was born in Vancouver, British Columbia. She is fluent in both Polish and English, as her mother is Polish and her father is Spanish American. She is trained in both Ballet and Jazz.
Campbell's career started with acting in television commercials at a young age.
She is known for her role as Maia Rutledge-Skouris on the USA channel miniseries and show, The 4400 (2004–2007). There she portrays a returned 'child abductee' who's been missing for decades. When 'returned', she is un-aged and imbued with the psychic ability to foretell the future.
She starred in 2004 in the small indie-film, Pursued, opposite Gil Bellows, Michael Clarke Duncan and Christian Slater. Though she completed a small role in Bob the Butler, her scenes were deleted. Her feature film debut ultimately came with Scary Movie 4, which set a box office record for Easter weekend 2006.
