Brooks Nader iced out her sister Grace Ann Nader for revealing her romance with her “man of the hour,” tennis pro Carlos Alcaraz.

“Did she really block you? She told me she blocked you,” Amanda Hirsch asked Grace Ann on Tuesday’s episode of her “Not Skinny But Not Fat” podcast.

“She blocked me,” the 25-year-old confirmed, with sister Sarah Jane Nader noting that the two “block each other all the time.”

Hirsch had texted Brooks the day Grace Ann spilled the beans to E! News to ask about having her sisters on her podcast; however, she insisted the inquiry had nothing to do with the Alcaraz revelation.

“I was like, ‘Hey! I need to have the sisters on!’ And she was like, ‘Oh, my God, I’m so mad at [Grace Ann] right now.’ Like, started telling me. I was like, ‘Oh, that’s what’s happening right now? Could you connect me to them?’” Hirsch recalled.

“What’s so funny is she was like, ‘She’s blocked right now, but hold on, I’ll connect you.’ And then she, like, does it.”

Grace Ann explained that Brooks, 28, “didn’t speak” to her “for a while.” But when the Sports Illustrated Swimsuit model was getting ready to appear on “Watch What Happens Live” a week later, their publicist told the fellow model that she needed to sit in the audience — mic’d.

“I was like, ‘Oh, my gosh. This is gonna be the death of me,’” Grace Ann thought to herself.

During the show, host Andy Cohen asked Brooks about Page Six’s exclusive reporting that she was actually seeing Alcaraz and his US Open finalist opponent, Jannik Sinner, simultaneously.

“A lady never kisses and tells, especially twice. That’s just not nice,” Brooks cheekily responded, prompting Grace Ann to chime in, “Especially not to her other boyfriend.”

Brooks defended her actions by adding, “I mean, ‘dating’ is such a loose term these days. … Guys do it all the time, so why can’t I do it?”

Grace Ann told Hirsch that she and Brooks “made up” after “WWHL” and that they’re “besties again.”

When the podcast host asked whether Brooks would make Grace Ann “sign an NDA at some point,” she made it clear she would not be doing that.

“Are you kidding me? Then what do I have to talk about on the press line?” she quipped.
