Donald Trump might have had his worst day ever ... but Stormy Daniels had her best day on a popular pornography website.
The good folks over at Pornhub tell TMZ ... Donald's arrest has been a boom for Stormy's adult videos, with searches for her pornos spiking while Trump was getting booked.
We're told Pornhub users searched "Stormy" more than 650,000 times Tuesday ... it's a staggering figure on its own, but when it's compared to her daily search average over the first three months of the year, it works out to a whopping 32,400% increase.
Seems like there's a lot of interest out there as to why Trump allegedly had an affair with her.
Diving deeper into the numbers ... by 1:00 PM ET, as folks were waiting for Trump's motorcade to arrive at Manhattan Criminal Court, Pornhub says "Stormy" searches were six times their normal level ... which usually isn't peak horny hours.
Trump flew back to Mar-a-Lago on his private jet after his first day in court ... but some folks still have "jail" and "prison" on the brain ... Pornhub says searches with those two keywords this week are more popular than normal.
Trump's accused of paying Stormy $130,000 to shut up about the alleged affair. As for how much Stormy is making off the recent spike in her videos ... Pornhub is mum.
Take that to the spank bank.
