Silverstone, now 44, starred as the endearing Cher Horowitz in the 1995 classic.

But while she’s a household name, it seems we’ve been pronouncing it wrong all these years.

The mom-of-one took to TikTok to clarify exactly how to say Alicia, as she stitched a clip on the site.

“Tell me what your name is, and then tell me what people mispronounce it as,” a woman says.

Silverstone, who joined the social media platform in June, captioned a clip: “Just an FYI… it’s Ali-SEE-yuh.”

The video has been watched more than 10 million times since being shared on Friday, as Silverstone revealed all the different pronunciations she has heard.

The Batman & Robin star said: “My name is Alicia, Ali-SEE-yuh, not Aleesha, not Alisha, Ali-SEE-yuh.”

She revealed she’s gotten used to the mistakes over the years, adding: “It doesn’t bother me though! But my sweet mama didn’t like it, so for her, Ali-SEE-yuh.”

Silverstone, who also shared the clip on Twitter and Instagram, shocked fans with the revelation, with even die-hard supporters admitting they’d been getting it wrong for decades.

StC Homebrew wrote: “No kidding, I am close to the same age as her so she has always been in the public eye to me, I never knew people didn’t know how to say her name. Pretty shocked.”

Alice_saberhagen commented: “What??? My whole life has been a lie.”

Autumn admitted: “Well it seems like I’ve been saying your name wrong my whole life.”

While 10k joked: “Her name is Cher, C-H-E-R people mispronounce it as Alicia.”

And Dana Marlowe said: “I want to apologize for saying your name wrong through the 90’s until today. Nice to meet you, Ali-SEE-yuh.”

While the TikToker she stitched the video of, Mahogany Lox, gushed: “Omg thank you for stitching my video!! Clueless is one of my all time fav movies. I even got a white Jeep and named it Cher! My heart.”

But it seems Silverstone has been attempting to correct people for years, after a superfan shared an article from Entertainment Weekly, printed on March 31, 1995.

It says: “As for Alicia’s name, you would be unwise to pronounce it poorly. Utter the syllables as if she’s a mere mall rat—A-lish-a—and prepare to be corrected. No! Her name, like her career, is far more luxuriant: A-lee-cee-a.”
