Selena Gomez revealed the big role her “Only Murders in the Building” co-star Martin Short will have in her upcoming nuptials to Benny Blanco.

“Marty is due to give a speech,” the actress said on Thursday’s episode of “The Drew Barrymore Show.”

“I told him he must … I feel like Marty would have an epic speech.”

Gomez, 32, joked that their fellow co-star Steve Martin would “probably pull out his banjo” and show off his musical skills.

Host Drew Barrymore wondered whether the pop songstress would have Martin, 79, and Short, 75, officiate the ceremony.

“Oh my gosh! I hadn’t even thought about that,” the Disney Channel alum responded.

Gomez and Blanco, 37, who confirmed their romance in late 2023, announced their engagement in December 2024.

“forever begins now,” she wrote on Instagram alongside photos from their special moment.

At the time, she showed off her giant marquise diamond from the music producer, which Page Six learned Blanco started designing in early 2024.

During her recent appearance on “The Tonight Show Starring Jimmy Fallon,” Gomez shared details about Blanco’s proposal, mentioning that she was feeling a bit unsettled before he popped the question.

The “Lose You to Love Me” singer recalled how Blanco asked her to come to set for their “I Said I Love You First” album.

She recounted, “I woke up feeling confused about our whereabouts and where we were headed, as it appeared to be quite a distance. I was a bit grumpy, very tired.”

Gomez shared she even told Blanco that she wanted to “go hang out with [her] friends” after they were done working.

The engagement then “went off without a hitch” and the “Wizards of Waverly Place” alum “freaked out.”

The duo said they’re taking their time with wedding plans and haven’t “figured anything out” yet.
