Ariana Grande Releases Her highly Anticipated 'Thank U, Next' Video

Ariana Grande's highly-anticipated "Thank U, Next" music video has finally dropped and it's everything we hopped for even an apology to her ex-fiance Pete Davidson.

During the "Mean Girls" portion of the video ... Ariana's "Burn Book" includes a page for Pete with the words "Sry I Dipped," "Love U Always" and "HUUUUUUGE."

Kris Jenner also made an appearance in the "Mean Girls" part of the vid ... playing Amy Poehler's "cool mom" character. As we first reported ... a Kardashian was gonna make a dancing cameo appearance. We didn't know who at first but later learned it was Kris, and the music video confirms it.

The music video featured scenes from 4 female-driven films that have special meaning to Ariana -- "13 Going on 30," "Mean Girls," "Legally Blonde" and "Bring it On."

Tons of celebrities made cameos to help AG pull it all off ... including Jennifer Coolidge, Jonathan Bennett and Troye Sivan.

There's even a shout out to Pete Davidson's nether regions ... Ariana has some dialogue with Coolidge where she mentions a boy with a "BIG" one ... she's dropped hints on Pete's genital size before.

Ariana's been teasing the video for some time now and released a behind-the-scenes teaser of the making of the music video.
