For Khloe Kardashian, having her ex Tristan Thompson get a vasectomy was a clear-cut decision.

After the retired NBA player admitted he had “enough baby mamas” (that total coming in at three), The Kardashians star revealed how she came up with a solution in a snap—or rather snip.

“Who helped you fix that decision? That was me,” Khloe—who shares daughter True, 8, and son Tatum, 3, with Tristan—said on the May 28 episode of her podcast Khloe in Wonder Land. “Tristan may have had a little ultimatum from me.”

And when it came to “getting neutered,” as the athlete put it, “sometimes you gotta lay them nuts on the table.”

However, Tristan—also dad to son Prince, 9, with Jordan Craig as well as son Theo, 4, with Maralee Nichols—suggested the vasectomy wasn’t that bad.

“It was 15 minutes,” he added. “It’s quick.”

Still, Tristan indicated he wouldn’t be interested in a reversal, as he added, “I’m not laying down on that table again.”
