With members of its cast ranging from Sting to Shirley MacLaine,Only Murders in the Buildingis no stranger to phenomenal (and occasionally unexpected) guest stars. But the murder mystery's newest addition might be its biggest yet: Meryl Streep.

That's right, Academy Award winner and living legend Meryl Streep is taking a trip to the Arconia for Season 3 of Only Murders in the Building. Streep appeared in a TikTok alongside the show's main trio of Steve Martin, Martin Short, and Selena Gomez. Also present were guest stars Andrea Martin, who plays Charles's love interest, Joy, and Paul Rudd, Season 3's murder victim.

Steve Martin also made the news of Streep's casting official with a tweet announcing the start of filming for Season 3:

• Is the liverwurst and marmalade sandwich from 'Only Murders in the Building' Season 2 as good as it sounds?
• The knitwear of ‘Only Murders in the Building’ is the show's secret weapon in cozy crime
• 'Only Murders in the Building' review: Season 2 can't stop hitting itself. That might be the point.
• Who wore it best: 'Halloween Ends' or 'Only Murders in the Building'?
• Early 2024 TV deals include several premium Samsung QLEDs and cheap TCL and Hisense QLEDs

So who will Streep play? Some estranged family member of our heroes, a fan of the Only Murders in the Building podcast, a new Arconia resident... or maybe even the murderer? Whoever she is, we are certain she'll be enthralling. Meryl Streep, welcome to the Arconia.
