Lively, 31, and Reynolds, 42, hosted a reception and special screening of Blunt’s Mary Poppins Returns in New York City on Thursday night which saw the trio reunite publicly for the first time since Blunt and John Krasinski’s premiere of A Quiet Place in April.
Reynolds shared photos of the group on Instagram, including a heartwarming picture of Lively and Blunt, 35, hugging each other and smiling at the camera.
“Emily Blunt is a master at work. She is brilliant. She must be stopped,” the Deadpool star raved in an Instagram post on Friday.
Lively, who is known for having effortless style, posted a solo shot from the premiere to tell fans that he look was channeling “”Cinderella post stepsisters tearing up her gown because they hate her” chic.”
Blunt kept it casual in an olive green top and matching high-waisted pants, and later adding a camel coat.
This isn’t the first time the famous friends have supported each other.
In April, Krasinski, 39, and Blunt received a show of support from Reynolds and Lively when the two attended the New York City premiere of A Quiet Place.
Krasinski directed and cowrote the horror flick, and also starred alongside Blunt.
Now, the actress stars as Mary Poppins in the sequel to the 1964 classic that earned Julie Andrews an Oscar for Best Actress.
Blunt was nominated for a Golden Globe Award for the role, as well as a Screen Actors Guild Award.
Mary Poppins Returns is now in theaters.
