Billie Lourd Will Honor Debbie Reynolds on Will & Grace in the Sweetest Way

It's been nearly three years since Hollywood legend Debbie Reynolds died, leaving a huge hole in the entertainment world. One of the many places in which her passing was deeply felt was on Will & Grace, where Reynolds was nominated for an Emmy for playing Bobbi Adler, the fabulously exuberant mother of Grace (Debra Messing).

Will & Grace paid tribute to Reynolds after her unexpected death with a gorgeous oil painting featured in an episode that went back in time. Now, the show's final season will feature another homage to Reynolds: a fitting cameo from Reynolds' granddaughter, actress Billie Lourd, who will play Bobbi Adler's granddaughter, TV Guide has learned.

Deadline, which broke the news, reports that in an episode taping Sept. 25, Lourd will play Fiona, the daughter of Grace's sister Janet (Mary McCormack). "The episode is especially meaningful because of Billie's relationship to the show," Will & Grace co-creator/executive producer Max Mutchnick told Deadline. "We're thrilled to have Billie. And best of all -- she's really good."

Get your tissues ready.

Will & Grace returns in 2020.
