Cher likes to text — a lot.

“You never know when they’re coming or what they might be about,” said Stephanie J. Block, who won a Tony Award Sunday night for portraying the pop icon in “The Cher Show.”

The moment Ms. Block’s win was announced, her phone lit up with messages. “She texted: ‘Oh my, oh my god, oh my god,’” Ms. Block said. “And actually, there were no emojis, which is major for Cher.”

After the awards, Ms. Block and several dozen other Broadway bigwigs (both literally and figuratively) crammed into the Carlyle Hotel for the annual after-party hosted by Rick Miramontez, the publicist, and John Gore, a producer.

Laurie Metcalf, a nominee for “Hillary and Clinton,” came early, settling into a corner banquette in the Art Deco lounge. Billy Porter entered, like Scarlett O’Hara, wearing a red velvet outfit made from the curtain from “Kinky Boots,” for which he won a Tony in 2013.
