Alicia even donned a version of her iconic yellow plaid blazer from the 1995 comedy that catapulted her to fame. And she got a little help from her son Bear, 10.
In the short clip, the star struts towards the camera as No Doubt's "Just a Girl" plays in the background. Bear, who she co-parents with her ex Christopher Jarecki, quickly pops into the frame before Alicia shrugs him off, lip-syncing to her own dialogue, "Ew, get off of me! Ugh, as if!” Bear then comes back in the scene for a hug and kiss from his adoring mom.
The footage -- which has garnered over 37.9 million views -- was captioned, "Ugh! As if... I wouldn't join TikTok." Alicia also shared it to her Instagram as well, writing, "I guess I'm on TikTok now🤷🏼♀️💛😘 #Clueless."
A few days later, "The Diary of a Wimpy Kid" star posted a TikTok of a fan edit of the clip, in which the user had edited her recreation of the "Clueless" scene with the original.
In the caption, Alicia thanked TikTok for "the incredible welcome."
"I'm totally feeling the love🥰 ," she wrote.
Although the star has only been on TikTok for a week, she already has 2.1 followers -- and counting!
