Larsa Pippen Says She's Not Banging Ben Simmons

Scottie Pippen's estranged wife, Larsa Pippen, says she is NOT hooking up with NBA superstar Ben Simmons ... adamantly denying she was getting close to the hooper earlier this week.

There were reports Pippen and Kendall Jenner's recent ex-boyfriend were looking like a couple at The Highlight Room on Monday night ... with the non-couple leaving within minutes of each other that night.

The news would be a MAJOR deal in the Kardashian world since Larsa is BFFs with Kim and Kourtney. #SCANDALOUS!!

But, Larsa is having NONE of that talk ... saying she never even saw the 23-year-old Sixers point guard that night ... and would NEVER betray a family friend a la Jordyn Woods.

"I never even saw him, let alone left with him," Larsa said in a heated IG story. "He dated my bff's sister and I would never."

Seems like a low-key shot at Woods -- Kylie's ex-BFF -- who hooked up with Tristan Thompson which led to a messy split with Khloe Kardashian.

Ben and Kendall dated for a year and broke up sometime around May ... and he famously dated singer Tinashe prior to that.
