Katie Thurston Jokes She’s Sharing Video From Heaven After Viral Death Rumor

Katie Thurston‘s sending a message from beyond the virtual grave … ’cause she’s joking that since social media says she’s dead, it must be true!

The former Bachelorette shared a clip on Instagram Saturday morning … thanking randos on Facebook for alerting her friends, family and even herself that she’d passed away after her battle with breast cancer.

She says she’s got a message while up in paradise — chilling with her pal God — for all of us still holding on tight to the mortal coil … before plugging a casket company she says won’t charge insane marked-up fees.

It’s a pretty hilarious clip … and, way different from Katie’s first reaction to the news — ’cause she dropped a vid Friday where she called the online rumor “triggering” while talking through tears.

KT says she got a ton of texts from people she doesn’t normally hear from … and, she says she’s unbelievably upset because there seems to be nothing she can do to shut the rumors down.

Thurston revealed in February she’s fighting breast cancer … and, it’s put her through the emotional gauntlet — feeling everything from despair to downright fury.
