"Big Bang Theory" actress Mayim Bialik has just sued over her serious car accident last year -- claiming it nearly cost her a hand.
As we reported, Bialik was driving in her white Volvo last August when it was struck by a 2013 Mustang in a Hollywood intersection. The other car was filled with Chilean tourists.
At the time, a source told us there was blood everywhere at the crash scene, stemming from major damage to Mayim's hand. Another source said "her finger was almost completely severed ... it was just hanging there."
Now the former "Blossom" star has filed a lawsuit against the other driver as well as Hertz Rent-a-Car -- presumably because the other car was a rental -- claiming she suffered injuries to her right hand, right thumb, and nerve damage.
She's suing for unspecified damages, but that includes lost wages -- and since she earns a reported 5 figures per episode on "Big Bang," it could really add up.
