Mayim Bialik, aka, Blossom was involved in a car accident yesterday afternoon in Los Angeles. And it was pretty serious. In fact, there was even a chance she might lose a finger.

Thankfully, that's not going to happen. She Tweeted, "In pain but will keep all my fingers." Actually, her husband had to Tweet that for her, because she really DID almost lose a finger.

Mayim was at an intersection in her white Volvo when she was struck by a vehicle filled with tourists from Chile.

A source says there was, "tons and tons of blood everywhere" and a finger on Mayim's left hand was, "almost completely severed . . . just hanging there."

There's no word whether anyone else was injured.

Mayim is more recently known to the youngsters as Amy Farrah Fowler on "The Big Bang Theory".
