Viola Davis Replaces Kylie Jenner in 'WAP,' Cardi Appreciates the Love

Fans were really down to insert Viola Davis into Cardi B's new song -- even at the expense of Kylie Jenner -- and the actress was all about it ... CB was too.

Viola posted a couple different fan tributes that creatively embedded her into Cardi and Meg Thee Stallion's music video for "WAP" -- one of which swapped VD's face and body for Kylie's. Viola seemed to think it was funny -- she wrote, "Who did this?" and added emojis.

She posted another fan rendition, which spliced in a scene of "How to Get Away with Murder" ... seamlessly syncing up Viola dancing to the "WAP" beat in the background. Viola liked that one too, reposting it and adding flamenco emojis with the hashtag #HowToGetAwayWithWAP.

That last shout-out caught the attention of Cardi herself, who appeared pretty starstruck with the love Viola was showing. She retweeted Viola's post with the caption, "I'm so fan out right now ya don't even know." Looks like both ladies are pretty fond of each other. Who knew?!?

The video's taken off since it was released last week ... it's already got 59 million-plus views, and it's spurred meme after meme after meme, including the Viola one you see above. Like we told you, the purpose of the project was to showcase women empowerment and solidarity.
