Rita Moreno will have Family duty in the near future…

The 81-year-old Puerto Rican actress/singer/dancer has joined the cast of NBC‘s new sitcom Welcome to the Family.

Moreno, who’ll receive the SAG Award‘s Life Achievement statue in January, will play Abuelita, the sassy grandmother of Lisette (portrayed by Justina Machado), who looms large over the Hernandez family.

Moreno’s character, expected to first appear in November, is described as extremely religious, judgmental, tough, perpetually scowling and rude. The thought of disappointing Abuelita is so unappealing that Lisette and her family tell her elaborate lies about their lives whenever she comes to visit.

Moreno is best known for her roles in West Side Story, The Electric Company and Oz. She’s also among an elite group of performers to have won an Oscar, Emmy, Tony and Grammy.

In addition to Moreno and Machado, the new comedy series also stars Ricardo Chavira, Joey Haro and Fabrizio Guido.

Welcome to the Family premieres Thursday, October 3 at 8:30 pm ET on NBC.
