Meryl Streep and Martin Short have a long friendship. Here's every time the 'Only Murders' costars have denied dating rumors.

Streep's casting was announced in a behind-the-scenes set video Selena Gomez shared on Instagram in January 2023.

On the show, Streep portrays Loretta Durkin, a struggling actor who lands the role of the nanny in Oliver Putnam's play "Death Rattle." It's later revealed that she was keen on being part of the play in order to reconnect with her estranged son, Dickie Glenroy (Jeremy Shamos).

Loretta and Oliver get to know each other before the play's opening night, and they begin dating.

During the season three finale, Oliver encourages Loretta to pursue acting jobs in LA, even though it would mean that they'd be living across the country from each other.

"It's pretty unexpected to imagine a pairing of Meryl Streep with Martin Short and watch them find this incredible connection together and, as Meryl said, to not have it be twee or about the age or about any of that," Hoffman told TheWrap, adding that Short brings "dramatic poignancy" to the dynamic.

Hoffman also said that Streep, who's been acting professionally since the '70s, ranked the ferry scene during episode five, in which Loretta and Oliver have a romantic date night, as one of her all-time favorite filming locations.

At the awards show, "OMITB" was nominated for best TV series — musical or comedy. Short was nominated for best actor in a TV series — musical or comedy and Streep earned a nod for best female actor in a supporting role on TV.

Two days after the Golden Globes, Short's rep said that the pair "are just very good friends, nothing more."

"We're not a couple. We are just very close friends," Short said during an interview for "Club Random with Bill Maher."

Short told People magazine that Streep called him prior to season three and asked about a role for her on the show.

"They already planned that I would have a theatrical experience and there would be a love interest," Short said. "So that was coincidental, but she just wanted to be on the show. She didn't know about [the love story]."

Hours before the premiere, The Hollywood Reporter published an interview with Short, in which he said he and Streep are just "friends."

The red carpet took place at Paramount Studios in LA days before the season premiere. Streep and Short were spotted holding hands on the carpet and at the after-party.

A source told Page Six that the costars were "in great spirits, laughing" at the after-party. Streep's rep also told the publication, "They are just friends."

In an "OMITB" cast interview with Extra, Short was asked, "Had your friendship grown since playing so close characters?"

"It's been a friendship that always grows if you work with someone and love that person," Short said, stopping himself because he didn't want to unintentionally reveal any spoilers about season four of "OMITB."

"Meryl is a friend to all of us," Steve Martin, who starred alongside Streep in the 2009 rom-com "It's Complicated," chimed in. "I very fortunately had a movie with her. If I don't see her for two years, you get back together and you're already laughing and talking. It's friendly."

Loretta and Oliver reunite in LA in the season four premiere, which is set a few days after the events of the season three finale.

In an interview with E! News, Short recalled having nerves on his way to his first day of work with Streep. As it turned out, Streep felt similarly.

"Then we finished a two-person scene at a piano, and they have to set up for angle and we went into a holding area, and she said, 'OK, my nerves are to half,'" Short said.

"I went, Oh, OK, that's, that's pretty cool,'" he continued. "'Maybe that's why you're the greatest actress, because you've never taken anything for granted.'"
