Whenever Martin Short is on a talk show, you know the first couple of minutes are going to be taken up with him mercilessly roasting the host. Seth Meyers is no exception. Appearing alongside Only Murders in the Building co-star Steve Martin in the Late Night clip above, Short skips the pleasantries to get a couple of early jabs in.

Steve Martin poked fun at the rumors that his “Only Murders in the Building” co-stars Martin Short and Meryl Streep are dating on Instagram Saturday. The actor, 79, posted a photo of the trio from a Glamour article, with a giant red X over Martin’s face. Martin did not add a caption to his post, letting the picture speak for itself.

Steve Martin posted an edited photo of himself, Martin Short and Meryl Streep on his Instagram on Oct. 18. A Martin fan account later shared the snap, with fans speculating as to whether the actor was 'confirming' a relationship between Short and Streep.

Martin Short and Meryl Streep are at the center of more than one unsolved mystery. There’s the one on season four of Only Murders In the Building, the Hulu show on which they co-star as love interests, but there’s also the haze of ambiguity around Short and Streep’s relationship in real life, fueled most recently by yet another night out together.

Steve Martin seemingly hinted at the Meryl Streep and Martin Short romance rumors. On Friday, October 18, Martin, 79, posted a screenshotted photo via Instagram of himself, Streep, 75, and Short, 74.
