Billie Lourd, daughter of the late Carrie Fisher, has announced the arrival of her first child with her fiancé Austen Rydell.
The American Horror Story actress made the surprise announcement in a post on Instagram, having seemingly kept the entire pregnancy a secret from the public and even some of her co-stars.
Billie, of course, made sure to pay tribute to her beloved mother, who died in December of 2016 after suffering a cardiac arrest at the age of 60.
Check out footage of Carrie Fisher, famous for playing Princess Leia, auditioning for the role with Harrison Ford:

Indeed, in the caption to a snap of the newborn's feet, Billie wrote: "Introducing: Kingston Fisher Lourd Rydell." The baby boy is also dressed up in what looks like a Star Wars baby grow.
The arrival of baby Kingston comes just three months after the 28-year-old actress confirmed she was engaged to Austen.
Needless to say, there were some very touching responses to the post, with one of Carrie's Star Wars co-stars Mark Hamill congratulating the pair.
He wrote: "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."

Zelda Williams, daughter of Robin Williams, took to the comments to write: "Yaaaaay! Congrats lovebug, and a big socially distant squeeze to you and to the new littlest Lourd!" alongside a heart-eyes emoji.
Billie's Scream Queen co-stars Emma Roberts and Lea Michele (who recently gave birth to a baby boy herself), also congratulated the actress.
Emma Roberts wrote: Screaming!!! "Love you guys so much", while Lea Michele added: "He’s finally here! So happy for you! Boy moms!"
Scream Queens actor Jamie Lee Curtis' comment on the post revealed she had not been aware that her co-star was even expecting. "WAIT WHAT????" she wrote.
Billie, who portrayed Lieutenant Connix in the Star Wars sequel trilogy, is the only daughter of talent agent Bryan Lourd and Fisher.
