Billie Lourd To Play Her Late Grandma Debbie Reynolds' Granddaughter on 'Will & Grace'

We already knew the final season of the return of Will & Grace would be emotional, but a recent casting announcement has increased that tenfold.

Debbie Reynolds brought to life Bobbi Adler, Grace's mother, on the original run of the show.

The character was a fan favorite, and despite only appearing in ten episodes had a lasting effect on audiences and the cast alike.

The revival of the show occurred after her passing in 2016.

In her honor, the show ran a tribute episode in its revival where Grace's family came together to celebrate the birthday of their mother, who had passed away sometime before the season started.

The show has now announced they will be honoring the actress in another way.
