Maybe Only Murders in the Building has a blank space on the call sheet for Taylor Swift.

Selena Gomez and her costars Steve Martin and Martin Short have some thoughts on if the “Karma” singer—fresh off the European leg of her Eras Tour—will make an appearance in a future episode of their hit series.

“You’re hilarious,” Selena told E! News correspondent Will Marfuggi in an exclusive interview airing Aug. 27. “She’s a little busy, you guys.”

But the Rare Beauty founder teased it could be her wildest dream come true to have Taylor make a cameo, adding to the show’s all-star cast lineup including Meryl Streep, Melissa McCarthy, Eugene Levy, Zach Galifianakis and Eva Longoria.

“Oh dear,” the 32-year-old said. “I love that.”

Steve Martin and Martin Short Playfully Suggest Taylor Swift’s Involvement

While Selena—who is nominated for her first acting Emmy for outstanding lead actress in a comedy this year—did not confirm whether or not her friend Tay will make an appearance, her fellow castmates had some fun with the suggestion.

“Listen, she calls us every day,” Steve joked of Taylor. “Here—she’s calling right now. Ahh I’ll take it later.”

Martin chimed in by saying, “No, I was talking to Taylor around 3:00 a.m.” (For more from Selena, Steve and Martin, tune into E! News tonight, Aug. 27 at 11 p.m.)

Steve Martin Praises the Friendship Between Selena and Taylor

All jokes aside, the Father of the Bride actor had praise to heap upon the longtime besties.

“Here’s how I unite Taylor Swift and Selena,” Steve continued. “Taylor Swift handles everything perfectly and so does Selena. In the situations I’ve seen—politically, trolls, everything—she just seems to have a wisdom about how to do something quietly, effortlessly. And I know that you have to think about these things.”

In response to her costar’s kind words, Selena appeared sentimental and said, “I wish I was recording that to send to her.”

And this isn’t the first time the Only Murders actor and co-creator has gushed over the Wizards of Waverly Place alum.

“When we first met Selena, she was already self-possessed and dignified and sophisticated,” Steve told E! News at the Aug. 22 Los Angeles premiere of season four, which hits Hulu Aug. 27. “If anything, we’ve just seen that creep up a little bit, as it should with maturity. But she was already there—a real person we admired and respected.”

And the feeling is mutual, as Selena responded during the joint interview, “It’s just been a joy to have people I can look up to and just be reminded that life is good.”
