Bellator champion Johnny Eblen's bank account took a big hit this weekend ... 'cause he treated an OnlyFans model to a day full of luxury shopping -- and the final price tag is wild!!
TMZ Sports has obtained video of the undefeated middleweight fighter's spending spree with Jessenia Rebecca -- who boasts nearly two million followers on Instagram -- and the two were clearly able to find what they wanted ... as they were both holding several bags.
We're told Eblen dropped $30,000 at Alex The Jeweler's shop, $25,000 at Dior and another $30,000 at Louis Vuitton ... totaling a staggering $85,000!!!
No word what inspired it all -- JR isn't even JE's girlfriend, but we're told he's currently in an open relationship with another lady.
