Billie Lourd Welcomed a Baby Boy

Billie Lourd Stands in for Mom Carrie Fisher for a Star Wars Reunion Photo

Lourd led an emotional tribute to her late mother at a fan event, and afterward posed for a touching photo with Star Wars creator George Lucas.

Billie Lourd and her fiancé, Austen Rydell, welcomed their first child together. In a surprise Instagram post, Lourd introduced her followers to her son — and, of course, his name honors the late Carrie Fisher.

Entertainment Tonight reports that Lourd had not previously revealed that she was expecting. Three months ago, the two announced their engagement. The two had been dating since 2017 after meeting in 2016, breaking up and getting back together.

The photo isn't a full-on face shot of the new baby, just a peek at his feet while he's wrapped up in a blue blanket.

"Introducing: Kingston Fisher Lourd Rydell," she wrote, adding a sprinkling of blue heart and crown emoji.

Back in July, Rydell shared a tribute to Lourd to celebrate her birthday. There were no clues or peeks at her pregnancy at the time.

"Happy Birthday to my FIANCé @praisethelourd !!" he wrote. "Your birthday feels like my birthday! I [love] you!! Here we go!!!"
