Jesse James lost his pinky while working with a saw at his custom bike shop.
And it's pretty gruesome. "Doesn't look like this little dude's gonna make it, Nice know'n you little buddy," James posted on Twitter Tuesday, sharing a stomach-churning photo of the severed phalange.
"OOOpps, Bad day at the office. Headed 2 Surgery in a few #PayUpSucker," he later added with another graphic photo of the sliced digit.
James, 44, rose to fame with his West Coast Choppers brand and Texas-based custom motorcycle shop, which gained him more notoriety when it got its own reality TV show on the Discovery Channel in 2002 called "Monster Garage" and later had a stint on "The Apprentice."
He also made headlines with a cheating scandal in 2010 that ultimately ended his marriage to Oscar winner Sandra Bullock.
