Anthony Ramos vividly remembers spotting Madonna in the audience of one of his “Hamilton” performances — but for all the wrong reasons.

During his guest appearance on Thursday’s episode of “Watch What Happens Live,” host Andy Cohen asked the Broadway star, “Who was the most terrifying celebrity to spot in the audience during your ‘Hamilton’ days?”

“The most terrifying was Madonna with her iPad in her face,” Ramos, 33, replied.

“She was like this the whole time,” he continued, imitating Madonna, 66, looking down at a tablet.

Ramos said he could tell by the “Material Girl” singer’s distracting antics that she was not impressed by his, or rest of the cast’s, performance.

“I was like, ‘Damn, shorty.’ I’m like, ‘If you’re not enjoying it that much, you know, the door is right there,’” he recalled thinking. “You ain’t got to stay here.”

Back in April 2015, Playbill reported that Madonna attended the Broadway show at The Public Theater — but was not invited backstage after it wrapped “due to her lack of theatre etiquette.”

“Tonight was the first time I asked stage management NOT to allow a celebrity (who was texting all through Act 2) backstage. #noselfieforyou,” Lin-Manuel Miranda, who created and starred in “Hamilton,” wrote in a since-deleted tweet at the time, per Playbill.

A source told the outlet that the songstress arrived late to the show and proceeded to take out her phone “several times” during the first act.

“She continued to use her phone, which glowed brightly in the Public’s intimate Newman Theater, throughout the second act,” the insider added.

Reps for Madonna did not immediately respond to Page Six’s requests for comment.

“Hamilton” debuted off-Broadway in early 2015, with Ramos portraying the duel role of John Laurens and Philip Hamilton, the son of the titular character played by Miranda.

He exited the award-winning musical in November 2016, going on to star in movies like “In the Heights,” “Dumb Money” and “Twisters.”
