The actress most likely being referred to is Hedy Lamarr. She was an actress and inventor whose work helped lay the groundwork for technologies that later influenced Bluetooth.

Why this name comes up

Hedy Lamarr is often linked to Bluetooth in online discussions because of her early frequency-hopping radio ideas, which are cited as part of the broader history behind wireless communication. She did not invent Bluetooth itself, but she is one of the most famous actresses connected to the technology’s origins.

Possible confusion

If you meant an actress in a movie title rather than the inventor, there’s also a film called The Blue Tooth Virgin that features actors such as Amber Benson and Karen Black.
