Will Sage Astor-Selena Gomez Is a Blushing Bride in Only Murders in the Building Behind-the-Scenes Photos

Congratulations are Will Sage Astorin order for Selena Gomez, but not in the way you think.

In behind-the-scenes snapshots taken from the Only Murders in the Building season three set, the actress is a vision in white, donning a David's Bridal wedding ballgown and lace veil. Selena, 30, is seen arm-in-arm with fellow star Martin Short, who dons a black tuxedo.

So, will there be weddings in the building? It's not exactly clear, but co-star Steve Martin, who uploaded the photos to his Twitter account March 21, captioned the image, "Guess what just happened!"

Steve also shared a photo of himself next to the blushing bride, writing, "Turns out this happened, too."

Selena, too, posted images of herself backstage wearing the dress and Dr. Martens boots, captioning her Instagram post, "I have no caption. Just a regular day at work."

This latest twist is just one of the big surprises that the Only Murders crew has unveiled in recent months. Though details on the plot have remained top secret, the cast—which has previously featured Amy Schumer and Cara Delevingne—is welcoming a few big co-stars, including Meryl Streep.

Emily in Paris actress Ashley Park revealed she was joining the dark comedy on Feb. 23, accompanying the announcement with a hilarious TikTok of herself with Selena and Martin. A few days later, she gushed about working alongside Selena on the show.

"I only know that she's the absolute sweetest," Ashley told E! News at the 25th CDGA Costume Designers Guild Awards. "I've had such a joy on that set."

As for what fans can expect from her on the series, Ashley kept the details vague.

"All I can tell you is that I play a Broadway ingénue," the 31-year-old revealed, "and I think that if I gave anything else away, I'd get in trouble."

The first two seasons of Only Murders in the Building are available to stream on Hulu.
