Mila Kunis -- who's about to pop out a little bambino -- found the easiest way to babyproof her L.A. mansion ... just get rid of it ... and make a million bucks in the process.
Kunis sold her Laurel Canyon digs Wednesday for $3.825 million -- slightly less than her asking price. She bought the 4,900 sq. ft. 5-bedroom crib back in 2008 for $2.885M.
As we've reported ... her fiance Ashton Kutcher is currently trying to unload his pad in Lake Hollywood Estates for $12 mil. They've already bought a place together in the Bev Hills area for $10.2M.
