Caitlin Clark has turned John Cena into a huge fan of hers -- because after the Iowa star hit the wrestler's signature celebration during a historic game Sunday night ... he showed her big love on his social media page!!!
Clark went crazy in the Hawkeyes' 97-83 win over Louisville in the women's NCAA tournament's Elite Eight ... and at one moment in her triple-double performance, she broke out Cena's signature "You Can't See Me" move.
The gesture was, of course, fitting .
