Jennifer Coolidge has finally joined TikTok and enlisted none other than Jennifer Lopez to help her film her first video.

The clip, which was viewed more than 3.4 million times in its first 15 hours on the platform, sees the Legally Blonde legend tell fans about what content she has decided to make.

“Hi, this is my first TikTok and I was trying to think of something cool to do and I think I’m just going to do a poem that I like,” she explains in the now-viral video.

Coolidge proceeds to read her “poem”, though it quickly becomes clear that she is in fact saying the lyrics to J.Lo’s hit single Jenny from the Block.

The camera eventually pans to the star, who appears to approve before declaring: “I like that, I really, really like that.”

Fans were left gagged by the collaboration and swiftly sounded off in the comment section.

“The queen has arrived,” one person wrote. “Everyone make way.”

“This TikTok deserves an Emmy,” added another.

A third said: “Screaming, crying, throwing up.”

The official account for the Empire State Building was among those excited to see the legendary actress on TikTok.

“COME TO THE EMPIRE STATE BUILDING FOR A VIP VISIT WE WOULD LOVE TO HAVE YOU QUEEN,” it commented.

Reese Witherspoon simply commented three laughing emojis to welcome Coolidge.
