How Billie Lourd Honored Carrie Fisher With Her Baby's Name

Congratulations are in order for Billie Lourd and her fiance of just a few months, fellow actor and producer, Austen Rydell. The couple announced the birth of their son on Instagram Thursday night, and fans of the Booksmart actress and her late, great mom, Carrie Fisher, are bursting with tidings over the news (via People and Elle).

Proud new mom, Lourd, posted a photo of a pair of adorable little baby feet, fittingly dressed in a space-themed onesie, with the caption, "Introducing: Kingston Fisher Lourd Rydell," accompanied by blue hearts and crown emojis. The nod to her mom, through both the middle name of her firstborn, Fisher, and the planetary pj's, was not only a heartfelt tribute to an esteemed actress, beloved for her role as Princess Leia in the Star Wars franchise, but also a fitting reminder to fans that the legacy of this Hollywood dynasty continues (via Elite Daily).

The birth of Carrie Fisher's grandson was celebrated with best wishes

Growing up the daughter of an A-list actress and top Hollywood agent, and granddaughter of icon Debbie Reynolds, it's understandable why Billie Lourd is notorious for keeping her private life out of the media (via Page Six). Her pregnancy was no exception.

With the happy news of Kingston Fisher's arrival being a surprise to everyone, including fellow Scream Queens cast member and expectant mom Emma Roberts, the well-wishers flooded social media with happy congratulations (via US Magazine). In the comments to her post, Roberts wrote, "Screaming!!! Love you guys so much." Lea Michelle commented with, "He's finally here! So happy for you! Boy moms!" And Rosanna Arquette posted, "Oh my God. Blessings to you... angels surround you both especially mama Carrie and grandma."

Mark Hammill, who famously co-starred with Carrie Fisher as Luke Skywalker, took to Twitter to send his love to the new parents, writing, "Congratulations to #BillieLourd & #AustenRydell on the arrival of their firstborn child: Kingston Fisher Lord Rydell!!! I can't think of another baby with both 'KING' AND 'LORD' in their name. Nice."
