Actor Michael Rapaport upset Ariana Grande fans Wednesday when he tweeted negative comments about her looks.

Ariana Grande is 27 acts 12, you take off those boots she hides her legs in, the cat eye make up and the genie pony tale and I think there’s hotter women working the counter at Starbucks no disrespect to Starbucks.

Readers quickly pointed out that Grande is 25, not 27. They also knocked Rapaport, 48, for his “totally inappropriate” words.

She’s probably only like 18 in this picture. And looks great without makeup. — Danny (@aridaenarys) December 19, 2018

Mikey, why the hate man? — Isitoveryet (@musco22) December 19, 2018

Another old man telling a young woman her worth only resides in her looks and tells her it’s not enough. Dude, your career went down the drain long ago, YOU ARENT RELEVANT ANYMORE. Also, this tweet is actually acting 12.. — Holly (@GraceTumblr) December 19, 2018

You know I ride for you 10/10 times @MichaelRapaport but why are we shaming @ArianaGrande without makeup on? You have a loud voice and large reach don’t let this be a moment where young girls feel they need to be in costumes or full makeup to be beautiful 🙏🏼 — MILK TYSON (@MILKTYSON) December 19, 2018

Thank you for doing this. I often wake in a cold sweat wondering what a nearly 50-year-old man thinks about Ariana Grande’s looks. I’m glad it’s finally settled. — Mad Sweany (@JRobertSweany) December 19, 2018

The Atypical actor, comedian and podcaster wasn’t fazed and fired back at commenters.

In other posts Wednesday, he wrote that one of the topics on the latest episode of his podcast, “I Am Rapaport,” is “social media snowflake hypocrisy.”

Earlier this week, Rapaport apologized for comments he made about Grande’s former fiancé, Pete Davidson, after he learned Davidson had posted a troubling message on social media.

Didn’t realize Pete Davidson posted an actual genuinely scary IG note.

Had no clue. Was not informed of all of those details. Would never mock someone when they’re truly down.

Sincerely.

I thought this was all the daily normal gossip of the day & was doing my daily take. — MichaelRapaport (@MichaelRapaport) December 15, 2018
