Mila Kunis is a total hero! No, legit, she totally is.
A man who was working at her house suffered a seizure while he was working and Mila came to his rescue.
A person on scene tells us ... Mila came running, had her friend call 911, then rushed to the man's side.
We're told the 28-year-old actress grabbed the man's head ... turned it to the side so he wouldn't choke ... while another person stuffed a wallet in his mouth so he wouldn't swallow his tongue.
Law enforcement sources tell us ... paramedics arrived on scene, rushed the man to the hospital, and he's since made a full recovery. We're told Mila volunteered to ride in the ambulance, but it wasn't necessary.
Just like Patrick Dempsey last week, we guess saving someone is the "new thing" in Hollywood -- while being seen at a Kings of Leon concert or Coachella is just pain out!
