Sesame Street star Alaina Reed Hall has died, aged 63.
The actress passed away on Thursday. The official cause of death has not yet been confirmed, but Hall battled breast cancer for several years.
Hall began her career in Broadway and off-Broadway productions, including Chicago and Hair, before being cast as Olivia on classic kid's show Sesame Street in 1976.
She also starred in popular U.S. sitcom 227, and began a romance with her co-star Kevin Peter Hall, who she later married both on and off-screen.
The actor died from pneumonia in 1991.
