Kelly LeBrock
-- the sexy former star of Weird Science -- has now been charged with a DUI ... after blowing TWICE the legal limit, TMZ has learned.

According to law enforcement sources ... the former Mrs. Steven Seagal blew a whopping .16 after she was pulled over for driving erratically around Santa Barbara last November.

She faces a $1,000 fine and up to 6 months in the slammer -- the reality ... she'll get probation and an alcohol ed course.

We reached out to Kelly's rep ... so far no word back.
