MAYIM BIALIK: Seriously Injured in Car Accident

Mayim Bialik was seriously injured in a car accident Wednesday in Los Angeles -- and, according to TMZ, she could lose a finger.

The Big Bang Theory star was traveling alone in a white Volvo when she was struck at an intersection by another vehicle filled with tourists from Chile. A source tells the gossip blog that there was "tons and tons of blood everywhere" and that the former Blossom star suffered major damage to her hand -- "her finger was almost completely severed... It was just hanging there."

Mayim later tweeted from the hospital that she will "keep" all her fingers, but admitted her husband had to type the message.
