A rep for the Blue Lagoon star confirmed to E! News today that Teri "passed away peacefully" in New York on Oct. 31.

Before Teri became her daughter's full-time manager when Brooke first entered showbiz as a child, the New Jersey native was herself a model for Lord & Taylor department store, as well as a makeup artist, hair stylist and a hostess at the famed Gaslight Cafe in Greenwich Village.

She married Brooke's father, Francis Alexander Shields, in 1964, but they divorced when their daughter was 5 months old. Francis died in 2003.
