After Star magazine published a story claiming the expectant star and her hubby-to-be started getting frisky at Laurel Pet Hospital in West Hollywood, Calif., while a vet tech examined their pooch, the mama-to-be has taken to her WhoSay page to slam the ridiculous rumor.
"Haha this is gross. Obvi this never happened and if I ever WAS turned on around the smell of dog piss I certainly wouldn't apologize for it," the House of Lies star fervently wrote.
The tabloid tale went into great detail over Bell and Shepard's supposed animal hospital hookup, claiming "they were basically on the exam table" and insisting that Kristen apologized afterward, explaining her "pregnancy hormones just made Dax irresistible, even in the vet's office."
And while we agree Bell's Parenthood beau is pretty irresistible, Kristen insists the story is a complete fabrication.
"Thanks to whichever dude at the Laurel Pet hospital had the integrity to make up and sell a story," she said. "You are a real piece of s--t. See you never again!"
And if that's not enough, the blond beauty also took to her Twitter page to slam the grotesque gossip:
"also I'm super horny so I think I'm gonna see if @daxshepard1 will meet me at the vets office for a quickie."
Zing! Case closed.
