The third season of Only Murders in the Building is getting added star power .

Selena Gomez , who plays Mabel Mora in the hit whodunit, announced via an Instagram video Tuesday that Oscar winner Meryl Streep has joined the cast.

Hey guys, were on set, Gomez says in the clip. What are we shooting? Season 3. The gang is back, yay. Could this honestly get any better?

The video cuts to Paul Rudd, whose second-season cameo reportedly preludes more screen time in the next installment of the show.

Well, I do think it could get a little bit better, he claims, before Streep pops up behind Gomez to ask co-stars Steve Martin and Martin Short if they need anything, revealing little else about the role shell play.
